The DQA1 gene is a member of the highly polymorphic MHC class II locus that is responsible for the differences among individuals in immune response to infectious agents. In this study, the authors performed a comprehensive computational analysis of the…
There are increasing concerns about the impact of agriculture and livestock production on the environment. As a result, it is important to have accurate estimations of greenhouse gas (GHG) emissions if reduction measures are to be established. In this study…
Data collected on metabolizable energy (ME) intake and growth performance of preruminant female kids of the Murciano-Granadina breed was used to assess the accuracy of the latest U. S. National Research Council (NRC) recommendations to predict their energy requirements. Female…
An investigation was conducted into the effects of sodium hydroxide treated maize straw on the water intake of milch goats when fed alone or in a complete mixed diet. Dry matter intake was more closely related to water intake than…
The effect of different periods (12, 14, 16 or 18 days) of intravaginal progestagen treatment (MAP) and PMSG (300 IU) on synchronization of oestrus in Boer goat does was investigated. No significant difference in oestrous response, follicular activity, ovulation rate,…
The proportion of eight fatty acids( 14:01, 6:0,1 6:1, 17:0, 17:1,18:01,8 :1and 18:2) was measured in the subcutaneous and kidney fat depots of five groups of Boer goat castrates which had been kept for 90 days on one of five…
The administration of different doses (62,5; 125 or 250 μg per injection) of a prostaglandin analogue (cloprostenol) 14 days apart (in the double injection regime), proved that oestrus can be synchronized very efficiently in the Boer…
The effect of supplementation on the milk production of Boer goat ewes maintained under veld conditions (grass-/bush community) was studied over a 12-week lactation period. An average of 625 g concentrates was consumed per ewe per day. Supplemented ewes produced…
Levels of sheep and goat production, as well as aspects of the distribution of ownership of pigs and poultry, in three livestock-producing areas of Ciskei are discussed. Findings show low levels of production and reproduction and high mortality rates in…
The aims of this research were to study goat production in the rural areas of South Africa and to explore the impact of intervention objectives, namely an increase in kidding percentage and a decrease in kid losses (mortalities, theft and…
In order to study the embryo recovery rate using the transcervical technique in Saanen goats raised in the tropics, 20 donors were submitted to an oestrus synchronisation treatment using intravaginal progestagen sponges for 11 days. On the ninth day of…
The aim of this experiment was to evaluate the efficacy of Neem seed extract (10% water solution) for tick control in goats in the Kilimanjaro area of Tanzania. Eighteen Small East African (SEA) and Toggenburg (TB) female goat kids between…
Infection with gastrointestinal nematodes (GIN) is a primary constraint to economic goat production in the southern USA. Anthelmintic resistance is highly prevalent in goat nematodes in this region, and non-chemical control methods are needed. Grazing of forages containing condensed tannins…
Four different goat ecotypes are recognized in Namibia. These ecotypes represent a unique genetic resource due to their adaptation to the different environmental conditions. Sufficient phenotypic characteristics exist that distinguish between the ecotypes. This study is a first attempt to…
The study was conducted to determine mineral concentrations in diets selected by goats grazing a thorn shrubland in a semi-arid region of north Mexico. Three goats (38 ± 1.8 kg BW) fitted with oesophageal cannulae were used to collect monthly…
The vomeronasal organ (VNO) consists of paired, blind ending tubes on either side of the nasal septum. The VNO lumen connects to the nasopalatine canal and also to the oral and nasal cavities. The vomeronasal sensory epithelium is connected to…
This study evaluated the effect of level of by-pass protein supplementation (PSL) and body condition (BC) on ovarian activity and serum insulin (INS) concentrations on does. Does (n = 32, 19 mo.) with either a low BC (LBC = 2.1…
The aim of this study was to evaluate the qualitative and quantitative characteristics of down fibre production and of the percentage of active hair follicles in several genetic types of Italian goats. The trial was carried out in two regions…
A study was conducted on 14 ha of Caducifolia thorny forest with an average total dry matter yield of 800 kg/ha/year. The area of study was divided into two 7 ha camps. Thirty-five Alpine goats were allocated to one of…
