TL;DR: Some of the physiological features of ruminants defined as intermediate feeders like large salivary gland, the large absorptive area of their rumen epithelium, and the capacity to change rapidly the volume of the foregut in response to environmental changes are most likely responsible for the goat’s superior digestion capacity.

TL;DR: Need for further experimentation to characterize interactions among factors such as breed, age and nutritional conditions in the fatty acid composition of carcass lipids of goats so as to gain a fuller understanding of goat meat quality.

TL;DR: This paper reviews the use of some indigenous plants as anthelmintics in animals of Indo-Pak subcontinent and focuses on the exploitation of anthel mintic potential of plants indigenous to Indo- Pak subContinent.

TL;DR: The history, origin and characteristics of the South African Boer breed of goats are reviewed, and the prototype for the breed was selected from several existing breeds of goats in South Africa to achieve the present functional characteristics and type.

TL;DR: To optimise the reproductive efficiency in the Boer goat doe, it is essential that its reproductive potential be known and exploited.

TL;DR: This study indicated that meat production from sheep in Oman will be improved in form of higher BW gains and better carcass composition by increasing energy levels in the diet.

TL;DR: The Dorper is a hardy South African composite breed, derived from a cross between the Black-headed Persian and the Dorset Horn, that adapts well to a wide variety of environmental conditions.

TL;DR: In this paper, the authors measured the amount of alphas1-casein (αs1-CN), protein, fat, SNF and total solids in 125 goat milk samples.

TL;DR: The levels of potassium in cheeses were lowest among all the products including fluid goat milk, suggesting that a significant amount of K was lost during cheese manufacturing processes, and levels of all trace minerals were higher in yogurt and cheeses than in fluid milk.

TL;DR: Data collected on 3256 lambs born to Horro and Menz breed ewes single-sire mated to 71 rams at the International Livestock Research Institute Debre Berhan station between September 1992 and June 1996 were analysed for rates of survival and growth from birth to weaning.

TL;DR: There was improvement in all semen and spermatozoa traits with age, the means at 12 months being consistently superior to values at 6 and 9 months of age, and differences were attributed primarily to nutrition.

TL;DR: The PEG showed its capacity to neutralize the tannins allowing a better utilisation of tanniferous species, as well as increasing the milk production and the milk urea content increased as a consequence of PEG supplementation.

TL;DR: In this article, the relative increase in the CLA content of lamb tissues by dietary CLA supplementation (0.33 g/d for 21 days prior to weaning) to milk-replacer of preruminant lambs or by feeding linoleic acid rich oil (Safflower oil, 6% DM-SAFF) to weaned ruminating lambs with that of lambs receiving unsupplemented milkreplacer and pelleted feed.

TL;DR: It can be concluded that all the three methods for oocyte harvesting can be used for the collection of oocytes in sheep, without any detrimental effect on the subsequent maturation and fertilization rate.

TL;DR: Data from 522 lambs of the Timahdit breed representing 13 sires were used to estimate genetic parameters and showed no genetic antagonisms among the growth traits.

TL;DR: The existence of differences among rams within each breed in semen quality and quantity makes it necessary to perform a semen evaluation on individual basis in order to select the best males before they are used for breeding.

TL;DR: This short history of the Dorper sheep traces its background and the steps taken to develop that breed in South Africa.

TL;DR: The mean pregnancy rate achieved, is acceptable following fixed-time AI in both breeds and at both doses progestagen, regardless of breed.

TL;DR: Ewes in first or second lactation have a less favourable milk secretion status in relation to mastitis than ewes with a higher number of lactations, suggesting feed rations may be improved by offeringFeed rations that take into account this reduced capacity to mobilise body reserves.

TL;DR: Overall, collagenase had little or no influence in decreasing motility, percent live spermatozoa and acrosome integrity, whereas, it was effective in eliminating semen viscosity.

TL;DR: SC was suggested as the most appropriate selection candidate for the genetic improvement of both male and female reproductive performance in two fat-tailed sheep breeds, indigenous to the Ethiopian highlands.

TL;DR: The Improved Boer Goat is a remarkable small-stock ruminant that possesses distinctive qualities enabling it to excel as an efficient red meat producer and plays a supplementary role to other farm stock in increasing meat production per unit area, rather than being in competition with them.

TL;DR: Production performance and heritability estimates for these traits were markedly higher than that previously reported in South American camelids.

TL;DR: One dairy goat herd of mixed breeds was investigated for frequency of genetic variants of alphas1-casein (as1-CN) and relationships between the genetic variants, milk composition, coagulation properties, and breed.

TL;DR: The Dorper was superior in reproductive and growth traits to woolled and other indigenous breeds, however, there is a lack of information on the performance of the Dorper in cross-breeding systems.

TL;DR: Body and carcass composition were studied on 10 male and 10 female naturally reared llamas (Lama glama) and age and sex seemed to have no effects on the body and carcasses characteristics studied nor on the chemical composition of meat.

TL;DR: In this paper, the effect of supplementing 10 g/day of polyethylene glycol (PEG) on the performance of does grazing on Mediterranean woodland and scrubland was quantified.

TL;DR: Sexual activity, body size and testis growth in the prepubertal period were studied in five male lambs of each of four dairy sheep breeds and Friesland ram lambs had a greater scrotal circumference throughout the entire period studied.

TL;DR: The review revealed a lack on information on the grazing behaviour and diet selection of Dorper sheep under more intensive grazing conditions and a total lack of scientific information on other behaviour aspects of this unique breed.

TL;DR: It was concluded that under similar conditions, a dose as low as 40mg MAP could be effectively used for estrus synchronization in cyclic Merino ewes.
