The experiment was conducted on twenty (20) post-weaned, male crossbred Dorper lambs. Castration was performed before weaning using the rubber ring method, nine (9) weeks prior to the start of the experiment. Age at the beginning of the trial for all lambs was 12 weeks and average live weights were 17.7 kg (castrated) and 16.9 kg (intact). Followin...

Abstract: The categorization of livestock farming systems in the CARICOM region has been a major challenge, particularly in strategic planning for development purposes. The cost of milk production for the dairy industry is an integral component used for the evaluation and comparison of the efficiency of various dairy farming systems. Cost of produc...

ABSTRACT: The Jamaica Dairy Development Board (JDDB), established in 1999, performs three main roles of policy formulation, capacity building and industry regulation. In 2017, reports stated that Jamaicans were consuming half of the 105ml World Health Organization recommended daily minimum of milk requirement. Concerns have also been raised concern...

The dairy farming system cost of production model employed in Jamaica utilizes a 3x2 matrix of parameters to classify farming operations. The to major components however are land area and use of irrigation vs rain fed pasture management. The current study approached the analysis by contributing more parameters including; herd architecture, effectiv...

An assessment of the consumer behavior patterns in the market for dairy vs non dairy milk commodities.

The use of anthelmintic remedies in small ruminant production is widespread in Jamaica and the CARICOM region. Issues relating to the efficacy and cost of dewormers and anthelmintic resistance are of particular concern to stakeholders in the livestock sector. Studies have investigated the use of organic compounds, derived from local raw materials a...

An approach to computerized record keeping systems for small ruminant producers in the CARICOM region.

The objective of this study is to determine the courtship behaviour of male agoutis reared in an intensive production system. Six male and ten female agoutis were randomly selected and housed in individual cages. Six females together with the males were included in a 6 × 6 Latin Square Design experiment where the six females were introduced into th...

Animal management for breeding and marketing can be improved by precise measurement of desirable traits. Live animal body composition analysis facilitates the selection of animals that are best suited for the intended purpose. This study was designed to assess the accuracy of bioelectrical impedance analysis (BIA) predicted live body tissue composi...

Generally sheep heads and feet are discarded at abattoirs and butcher shops in the Caribbean. In some societies (Middle East and Norway) however, these parts form part of the local cuisine. In Trinidad and Tobago the head and feet otherwise regarded as offal are significantly underutilized compared to other offal parts such as the tripe and interna...

The profitability of growing-finishing lamb enterprises is plagued by the increasing cost of imported feed resources. This study was designed to assess the effect of different protein sources at different inclusion levels on growth performance and carcass quality traits of intact growing-finishing Barbados Black Belly lambs. The diets offered inclu...

Pre-wean performance of lambs from Barbados Black belly (BB) and West African (WA) type ewes managed at pasture at the Blenheim Sheep Multiplication and Research Project was studied. Lamb pre-weaning performance was analysed for the period 1999 to 2004. Birth weight, weaning weight and pre-weaning growth rate of lambs were analysed according to the...
