    ABSTRACT: The aim of the study was to evaluate body condition score (BCS) and somatic cell count (SCC) of milk in Turkish Saanen goats. Data were obtained from 95 goats during the morning milking. While a 1–5 scale was used to assess BCS, direct microscopy was performed to analyse SCC. Effect of stage of lactation (SL) and number of kids at birth (NK) were evaluated in three subgroups. While SL has not affected the parameters, goats with a single kid had significantly higher BCS (P < 0.05) than goats with twins. Correlation coefficient between evaluated parameters was estimated as weak (r = 0.08). In conclusion, milk SCC and BCS levels of Turkish Saanen goats were assumed to be in acceptable thresholds.

    ABSTRACT: A 42-day study was conducted to evaluate the effect of ground full-fat flaxseed supplementation on growth performance, carcass characteristics, α-linolenic acid (ALA), linoleic acid (LA) and organoleptic characteristics of broiler meat. A total of 200 one-day-old broiler chicks were randomly allocated to five experimental groups and were fed isoenergetic and isonitrogenous diets containing flaxseed at 0%, 2.5%, 5.0%, 7.5% and 10%. Flaxseed supplementation did not affect the weekly body weight of broiler chicks during the first three weeks, but thereafter it reduced significantly with increasing levels of flaxseed in the diets. Birds fed on 10% flaxseed showed a reduction of 10.08% in body weight as compared to the control group. Diets containing 5.0–7.5% flaxseed resulted in significantly lower weight gain, higher feed conversion ratio, energy efficiency ratio and lower protein efficiency ratio as compared to control and 2.5% flaxseed diets. The carcass characteristics data indicated a little variation in the evisceration rate and giblet among treatment groups, but the breast yield was significantly higher in control than flaxseed groups. The protein, fat and ash content of broiler meat were not affected with the level of flaxseed in the diets. However, the inclusion of flaxseed in the diets significantly increased the ALA in the breast and thigh tissues with no difference in the organoleptic quality of meat.

    ABSTRACT: The production commensurate with the demand for animal products including meat is increasing due to urbanization and increase in per capita income. However, meat and meat products meant for human consumption should also be safe and free from toxic contaminants. Presence of any xenobiotics in human food web is undesirable and unacceptable particularly in the wake of sanitary and phytosanitary (SPS) measures and strict regulations imposed by many countries on the ground of safety of health of the consumers. In the present study, certain organochlorinated pesticide (OCP) residues in tissues and in blood samples of goat were determined. All samples were analysed for residues of hexachlorocyclohexane (HCH) isomers, dichlorodiphenyltrichloroethane (DDT) isomers and metabolites, endosulfan isomers and metabolite, aldrin, heptachlor and dicofol. The tissue samples were extracted in soxhlet with hexane-acetone (1:1) and cleaned up by florisil column chromatography. The analysis was performed in capillary gas chromatograph equipped with electron capture detector (GC-ECD). The result indicated that 40% tissue samples were contaminated with HCH residues, while DDT and endosulfan were present in 32% samples. In blood samples, no HCH residue could be detected, but DDT and endosulfan were present in 10% and 30% samples, respectively.

    ABSTRACT: Forty crossbred steers (245 ±0.95 kg) were used in a 222-d feeding trial to assess the effects of a supplementation of chelated chromium plus extract enzymatically hydrolyzed yeast (Cr-EHY) on growth performance, dietary energetics and carcass characteristics in feedlot cattle finishing during high ambient temperatures. Treatments consisted of a steam-flaked corn-based finishing diet supplemented with 0 or 0.4 g/kg of diet with Cr-EHY (0.3 g/kg of Celmanax plus 0.1 g/kg of organic Cr). Steers were blocked by weight and randomly assigned to 8 pens (5 steers/pen). Both dry matter intake (DMI) and climatic variables were measured weekly and the temperature humidity index (THI) was estimated. Daily maximal THI that exceeding a THI value of 72 were reached in 213 days of the total 222 days that the study lasted (avg. THI=75.24). Daily intake of Cr-EHY averaged 2.56 g and represents a daily intake of 4.25 mg of Cr/head. During the initial 112-d period, Cr-EHY supplementation increased ADG (6.8%, P=0.03) but as a consequence of a tendency (P=0.07) to increase dry matter intake (DMI) with Cr-EHY supplementation, there were no advantages (P ≥ 0.70) on gain efficiency and dietary energetic. Cr-EHY supplementation did not affect overall (222-d feeding period) growth performance. Nevertheless, Cr-EHY supplementation increased LM area (6.8%, P < 0.01) and tended to increase retail yield (1.6%, P=0.07), and tended to decreased carcass fat thickness (10%, P=0.09). These results indicate that Cr supplementation has a modulating effect on carcass quality, and may enhance DMI and corresponding ADG of feedlot cattle during periods of high ambient temperature.

    ABSTRACT: The aim of the present study was to investigate the difference in meat quality between local Thai indigenous Upland Cattle (Bos indicus) and Charolais × generic Thai native cattle crossbreds (here: F2, 75% blood proportion of Charolais), an increasingly preferred option of farmers in Northern Thailand. Eight bulls of the F2-crossbred genotype and eight of the Upland Cattle genotype were fed ad libitum with grass and were supplemented with concentrate at 1.5% of body weight until they were on average 4 years old. In the Longissimus dorsi (LD) muscle, pH at 45 min and 24 h post-mortem as well as luminosity were lower and redness was higher in the F2-crossbreds than in the Upland Cattle. The beef of the F2-crossbreds also expressed lower drip, thawing and cooking losses. There was no difference in grilling loss. The LD of the F2-crossbreds contained less moisture and more protein, fat and cholesterol than that of the Upland Cattle, and was richer in total and soluble collagen. Still, the beef of the F2-crossbreds was scored as more tender and had a lower shear force. Additionally it was scored to have a higher intensity of beef flavour as well as off-flavour and an overall better acceptability. Overall this suggests that a clearly better meat quality can be achieved by the crossbreeding strategy, but this was associated with higher fat and cholesterol contents. Further studies have to show which part of the changes in meat quality resulted from the large differences in body size of the two genotypes. Consideration for or against crossbreeding have to include animal welfare and health aspects.

    ABSTRACT: The feasibility of alternate dairy control as an alternative to traditional dairy control was evaluated. Adjustment factors were obtained for morning (AM) and afternoon (PM) milkings and applied to animals subjected to alternate dairy control to estimate uncontrolled milking and total daily milk yield. Data was compiled from six dairy goat farms in the Metropolitan Region of Chile for animals with completed lactations (of 305 days) and with recorded date of birth and parturition, parity and a minimum of six controls per lactation (used to determine AM, PM and total production). Values were sorted by productive factors parity and lactation month. Statistical analysis was performed using the Number Crunchers Statistical System ®2000 (Kaysville, UT, USA) to obtain mean values and adjustment factors for each productive factor and to make possible their application on any animal presenting the minimum required information. Adjustment factors were applied to 8788 values to estimate total daily milk yield. AM values estimated more accurate totals than PM values. Analysis provided r 2 values of 0.9083 and 0.7593, respectively, and supported the reliability of applying calculated adjustment factors to one of two daily milkings. The alternate dairy control system represents a viable alternative for estimation of total daily milk yield.

    ABSTRACT: Chemical characteristics and ruminal degradability of barley straw when treated with dry application (spraying technique) of acid and alkali were studied over the adjusted pH range (1.5–12.5 by measuring titratable capacity). Enzymatic (a cellulase product) effectiveness was also examined on pretreated straw at pH 3.5, 4.5 and 11.5. Treated straws were then ensiled for four weeks. Results showed that the solubility of dry matter (DM) and hemicellulose (HC) was altered quadratically within the pH region, while that of cellulose (CL) and lignin displayed minor changes. Release of phenolic compounds and water-soluble carbohydrates increased linearly with increasing alkaline pH whereas, they were raised from pH 7 up to pH 2 and then decreased at pH 1.5. DM degradability was little affected under acidic conditions and the highest value was achieved at pH 2, whereas fibre components (HC and CL) degradability was orderly reduced towards zero with decreasing pH. Increasing pH with application of alkali led to a linear enhancement of DM, HC and CL degradability. An interaction between pH level and enzymatic treatment was detected, such that the degradability of pretreated straw at pH 4.5 was enhanced but no improvement was attained at pH 3.5 and 11.5 with enzyme addition. Dry processing of barley straw under acidic pH, increased fibre solubilisation, reduced ruminal fibre degradability and exhibited a positive effect on the efficacy of the exogenous enzyme, while alkaline pH, in particular pH 12, substantially improved the degradation of barley straw.

    ABSTRACT: The objective of this study was to evaluate whether wheat factory sewage (WFS) could partially replace barley grain in the diet of dairy cows without adversely affecting dry matter intake (DMI), ruminal fermentation, digestibility and milk production of dairy cows. Eight multiparous (60 ± 3 days-in-milk) Holstein dairy cows were used in a replicated 4 × 4 Latin square design experiment with four 21-d periods. The four diets (treatment) differed by partially substituting WFS for barley grain at the rate of 0% (WFS0), 4% (WFS4), 6% (WFS6) or 8% of dietary dry matter (DM; WFS8). DM content of diets decreased from 65%, 59%, and 57% to 54% by increasing the inclusion of WFS due to high water content of WFS (80%). DMI changed quadratically and tended (P = 0.08) to be higher for WFS4 (23.1 kg/d) than for other three diets which were similar (21.5 kg/d). Ruminal fluid pH linearly increased (P = 0.01) with increasing WFS in the diet. Ruminal concentrations of total volatile fatty acid (VFA; 100–103 mM), acetate (65–67 mM), propionate (24–25 mM) and ratio of acetate:propionate (2.68:2.89) were not affected by increasing the replacement of barley grain with WFS. Apparent total tract digestibilities of DM (67%), crude protein (CP; 68%) and neutral detergent fibre (NDF; 54%) were not different among treatments. Milk yield (averaged 40 kg/d) and milk composition were not affected by the dietary treatments. These results showed that the inclusion of WFS at rates of 0, 4, 6, and 8% in place of barley grain in dairy cow diets decreased DM content of diets, but had no adverse effects on DMI, rumen fermentation, digestibility and milk production responses. In conclusion, WFS can be a candidate by-product as an alternative feedstuff for the partial replacement of barley grain in lactating dairy cow diets and also considered as an alternative energy source in a cost-effective manner when the price is competitive.

    ABSTRACT: Medium rabbit breeds such as Californian (CAL) are generally regarded as most suitable for meat production on commercial farms. Despite the increasing scale of production, commercial rabbit breeding has not replaced traditional and organic small-scale farming systems which use various rabbit breeds and hybrids. The Flemish Giant (FG), the largest rabbit breed in the world, is widely used in small household farms. According to researchers, the progeny of FG does have a relatively high weaning weight, and bucks are deemed good paternal components in commercial crossing. The aim of this study was to compare rearing rate, body weight, daily gains, carcass dressing percentage and the percentage of primal cuts in the carcass in CAL and FG rabbits. Nutrient digestibility, nitrogen balance and nitrogen retention parameters were also compared in the studied breeds. In our study, CAL rabbits were characterised by better reproductive performance in comparison with FG rabbits. Despite the above, the observed daily gain values, daily nitrogen balance and retention parameters and carcass dressing percentages of the compared breeds suggest that FGs may be a good alternative to medium breeds such as CAL rabbits.

    ABSTRACT: Black francolin (Francolinus francolinus) is a game bird belonging to Phasianidae family. This species is native to Southern Asia, Middle-East and Caspian region including Turkey. Black francolins are popular game animals and they play an important role in biological control of pests. Nevertheless, studies conducted on this species are extremely rare. The objective of this study is to introduce a profile of serum biochemistry for wild black francolins and to determine variations between sexes. We have analysed 13 serum parameters for each gender separately. We sampled 20 clinically healthy, adult black francolins. Analysed biochemical parameters are as follows: aspartate aminotransferase, alanine aminotransferase (ALT), glucose, triglycerides, cholesterol, creatinine, uric acid, total bilirubin, total protein, albumin, globulin, sodium and potassium. Females had significantly higher levels of aspartate aminotransferase and ALT while males had higher cholesterol levels.

    ABSTRACT: Citrus peel, a by-product of citrus processing is a rich source of numerous bioactive nutrients. This experiment was conducted to evaluate the effects of dietary supplementation of Citrus sinensis peel extract (CSPE) on few production and quality traits of broiler chickens. Four hundred broiler chicks (one-day-old) were assigned to any of the five dietary treatments comprised of: basal diet for 42 days, or basal diet containing 1000 ppm or 1250 ppm CSPE for 21 days, or basal diet containing 1000 ppm or 1250 ppm CSPE for 42 days. Compared to the final weight of broilers on the basal diet (2426.3 ± 120.9 g), the supplementation of the diet with 1000 ppm CSPE for 21 days resulted in significantly (P P Keywords: Citrus sinensis; broilers; carcass characteristics; carcass fat; carcass quality Document Type: Research Article DOI: http://dx.doi.org/10.1080/09712119.2013.875916 Affiliations: 1: Young Researchers Club, Rasht Branch, Islamic Azad University, Rasht, Iran 2: Department of Animal Science, Rasht Branch, Islamic Azad University, Rasht, Iran 3: School of Agriculture and Food Science, Institute of Food and Health, University College Dublin, Belfield, Dublin 4, Ireland Publication date: October 2, 2014 $(document).ready(function() { var shortdescription = $(".originaldescription").text().replace(/\\&/g, '&').replace(/\\, '<').replace(/\\>/g, '>').replace(/\\t/g, ' ').replace(/\\n/g, ''); if (shortdescription.length > 350){ shortdescription = "" + shortdescription.substring(0,250) + "... more"; } $(".descriptionitem").prepend(shortdescription); $(".shortdescription a").click(function() { $(".shortdescription").hide(); $(".originaldescription").slideDown(); return false; }); }); Related content In this: publication By this: publisher By this author: Ebrahimi ; Qotbi ; Seidavi ; Bahar GA_googleFillSlot("Horizontal_banner_bottom");

    ABSTRACT: This study evaluated the potential of preparing fish silage (FS) as a low-cost, protein-rich supplement for livestock feeding in Oman from ground Indian oil sardines (Sardinella longiceps) using organic and inorganic acids. It was co-dried with wheat bran before being mixed with other feed ingredients and pelleted for feeding Omani sheep. Forty Omani sheep were offered one of five diets aiming to gradually replace soybean meal (SBM) with FS. The proportions of FS in the diet were 0, 50, 100, 150 and 200 g/kg, whereas the parallel SBM levels ranged from 17% to 0%. Animals were fed 500 g/d of the concentrates and allowed ad libitum access to Rhodes grass hay. A digestibility experiment was carried out on 12 sheep fed 0, 100 and 200 g/kg FS. The fresh FS dry matter (DM) was 393 g/kg and it contained 510 g/kg crude protein (CP), 220 g/kg ether extract (EE), 153 g/kg ash, 34 g/kg calcium (Ca) and 31 g/kg phosphorus on DM basis. The 75:25 silage:wheat bran mixture contained 883 g/kg DM and 390, 139, 120, 17, 17 g/kg DM CP, EE, ash, Ca and phosphorus, respectively. The FS amino acid contents were comparable to that of the SBM. No ill health signs were observed on experimental animals. There were no differences (P > 0.05) in digestibility coefficients of CP, acid detergent fibre and neutral detergent fibre between the 0, 100 and 200 g/kg FS diets. However, the 200 g/kg silage diet had lower (P Keywords: Oman; fish silage; sardines; sheep Document Type: Research Article DOI: http://dx.doi.org/10.1080/09712119.2013.875909 Affiliations: 1: Agricultural Experiment Station, Sultan Qaboos University, Al-Khod, Sultanate of Oman 2: Department of Animal and Veterinary Sciences, College of Agricultural and Marine Sciences, Sultan Qaboos University, Al-Khod, Sultanate of Oman 3: Centre for Excellence in Marine Biotechnology, Sultan Qaboos University, Al-Khod, Sultanate of Oman 4: Ministry of Agriculture and Fisheries, Sharqiyah Region, Ibraa, Sultanate of Oman Publication date: October 2, 2014 $(document).ready(function() { var shortdescription = $(".originaldescription").text().replace(/\\&/g, '&').replace(/\\, '<').replace(/\\>/g, '>').replace(/\\t/g, ' ').replace(/\\n/g, ''); if (shortdescription.length > 350){ shortdescription = "" + shortdescription.substring(0,250) + "... more"; } $(".descriptionitem").prepend(shortdescription); $(".shortdescription a").click(function() { $(".shortdescription").hide(); $(".originaldescription").slideDown(); return false; }); }); Related content In this: publication By this: publisher By this author: Al-Abri ; Mahgoub ; Kadim ; Al-Marzooqi ; Goddard ; Al-Farsi GA_googleFillSlot("Horizontal_banner_bottom");

    ABSTRACT: Two experiments were conducted to evaluate the effects of different levels of threonine:lysine (Thr:Lys) ratios on growth performance, blood urea nitrogen (BUN) concentration, and nitrogen balance in weaned pigs. In Experiment 1, a total of 90 weaned pigs (Landrace × Yorkshire × Duroc) with an initial average body weight (BW) of 6.57 ± 0.46 kg were allocated into three treatments for 35 days. Each treatment had six replicate pens with five pigs per pen. Diets were formulated with different apparent ileal digestible (AID) Thr:Lys ratios of 0.62, 0.67, and 0.72. Dietary AID of Lys and Thr concentrations were set at 10.8 and 6.7, 7.2, 7.8 g/kg, respectively. Throughout the experiment, average daily gain, average daily feed intake, and feed:gain ratio were not influenced (P > 0.05) by dietary Thr:Lys ratios. However, BUN concentration was increased (linear, P = 0.01) as the Thr:Lys ratio increased at day 35. In Experiment 2, a total of 24 weaned pigs with an average BW of 8.57 ± 0.32 kg were individually housed in metabolic cages and fed for 10 days. Dietary treatments were the same as in Experiment 1. Nitrogen intake, nitrogen excretion in feces and urine, and nitrogen retention were not influenced (P > 0.05) by dietary Thr:Lys ratios. In conclusion, increasing dietary AID Thr:Lys ratio (0.62, 0.67 vs. 0.72) could not improve the growth performance and nitrogen balance in weaned pigs.

    ABSTRACT: Cattle–yak, the first filial generation of yak and ordinary cattle, showed obvious hybrid vigor, but a difficult problem in crossbreeding and improvement of yak is that the males are sterile. Thus it is not possible to steadily utilize the heterosis. So the study of the mechanism of male sterility is still one of the most interesting fields in yak science. Therefore, this paper will review contemporary studies in cattle–yak male sterility including the process of spermatogenesis, development of genital organs, pituitary and endocrinology, biochemical genetics and candidate genes correlating spermatogenesis, etc.

    ABSTRACT: This study assessed In vitro inhibition of plasma and brain cholinesterases (ChE) by the organophosphate insecticides chlorpyrifos and dichlorvos in chicks at ages of 2, 10, 20 and 30 days. Plasma samples and whole-brain homogenates of each age group were pooled and ChE activity was determined by an electrometric method with or without the organophosphate (0.5 and 1.0 µM). ChE inhibitions were the highest in 2- and 10-day-old chicks (20–83%), followed by 5–73% inhibitions at ages of 20 and 30 days. Cholrpyrifos decreased plasma ChE activity only at the ages of 2 and 10 days by 21–75%. Dichlorvos decreased plasma ChE activity at all the ages tested (2–30 days) by 39–83%. The highest percentage of plasma ChE inhibition by chlorpyrifos and dichlorvos was in 2-day-old chicks. In the brain homogenate, chlorpyrifos decreased the ChE activity between ages 2 and 20 days by 20–62%. The highest percentage of brain ChE inhibition occurred at the age of 10 days and the least was at 20 and 30 days. Dichlorvos decreased brain ChE activity between ages 2 and 20 days by 24–74%. At the age of 30 days, only the higher concentration of dichlorvos (1 µM) decreased brain ChE activity by 27%. The data suggest an age-related differential In vitro inhibition of plasma and brain ChE s in chicks. In vitro ChE inhibition, though it does not exclude interfering factors, could be useful for initial screening of the inhibitory actions of organophosphate insecticides in chickens.
