High input feeding system results in better growth performance in goats as compared to low input feeding system. Traditionally goats are reared under low input system while to see the effectiveness of high input feeding system, current project was planned to study the growth performance and carcass quality among various classes of Beetal breed. Total 16 Beetal kids (12 male + 4 female) were selected considering 120 (±10) days average age and weight ranging 16 (±2) kg for male and 14(±2) kg for female. The kids from various classes were divided into four treatment groups designated as S1 (Entire male or not castrated), S2 (castrated at 4 mo), S3 (castrated at 6 mo) and S4 (female). Animals were castrated during pre-fattening period and managed under same conditions before fattening. The duration of the study was 120 days (60 days pre-fattening + 60 day fattening). Total 12 animals (randomly 3 from each treatment group) were slaughtered at the end of study for detail carcass quality evaluation. The average daily gain (ADG) was significantly affected (P<0.001) by the treatments. There was higher ADG noticed in S3 group (93.75 gm/d) as compared to S1 (90.42 gm/d), S4 (63.89 gm/d) and S2 (33.75 gm/d). Average daily feed intake was significantly (P<0.05) highest in S3 (878.00 gm/d). The serum cholesterol and serum glucose were also affected (P<0.05) by the treatments. There was non-significant (P>0.05) effect of treatments on the sensory panel score about color, chewability, flavor, tenderness and overall acceptability of the cooked meat. It is concluded that sex and castration affected the growth in kids while the carcass traits were not affected. The age of castration need consideration in Beetal kids because castration at early age adversely affected the growth of kids in this study.

from 0.5 to 2 ha). The second group (B, 34%) was defined as livestock farmers raising either pigs in a very integrated MFS, with use of byproducts from crops or cattle raising (combined or not with the SR and optimizing the use of natural resources). The 3 rd group (C, 54%) was composed of SR breeders (as the main activity), divided according to grazing pasture area: the small unit using less than 15 ha; the large unit using more that 40ha and the ones using the public natural areas (67 to 402 ha). The proportion of species cultivated as food are higher in A than in C: 73 vs. 55%. While the proportion of feeds that are forage species are 30, 36 and 42%, respectively. The different links between activities (crop and livestock) are explained in relation to the farm conditions but also according to the natural environment. The index of sustainability appeared to be better for the groups exploiting crops as in the A group or the MFS ''pig'' ones (with the use of by-products for feeding animals and herbs for health control). Conclusion In the fields of SR production, improving the reproductive performances of the SR, increasing the use of silvopastoral resources, and organising the milk and meat sectors are recommended. The importance of MFS for the future, the interest of local resources and non conventional practices of feeding and health control of the animals are highlighted for reaching sustainable production. This Cuban experience of SAP in the case of SR production could be shared with other farmers of the Caribbean.

All around the world, sheeps and goats play an important role in small scale farming systems. Goat farming is very beneficial from economic point of view. It provides many products but meat and milk are the major products. Goat meat has low level of calorie, fat and cholesterol so it is a healthy substitute to beef and lamb. Moreover goats also use extensively to provide milk for human consumption. It is easier to digest than cow's milk because it has smaller fat globules than cow's milk. In order to support metabolic process all living organisms require essential nutrients, to keep themselves alive so variations in animal diets may improve both the quantity and quality of the final products. In recent years, yeasts are gaining popularity in fattening system as a probiotics.Since yeast is robust with high viability under a range of environmental conditions and can be culture very easily so yeast cultures are more commonly used as a feed supplements in livestock feeding systems. These cultures have positive impact on microbial population in gastrointestinal tract and they increase the beneficial activities associated with these microorganisms that has indirect impact on animal performance. Saccharomyces cerevisiae and Aspergillusoryza are the most important yeast products and they are very significant for the manipulation of rumen metabolism.It is stated by most of the researchers that yeast culture supplementation has positive impact on carcass characteristics, nutrient digestibility, feed intake and the growth performance of the goats in cost effective way but on the other hand some of the scientists do not support that results and they concluded that yeast supplementation in the diet of goats and other ruminants do not have any significant influences on animal performance, carcass characteristics and other features.Step by step, this paper will make the detail evaluation of the use of dietary yeast and its product in the feeding regime of meat type goats, impact of yeast on goat physiognomic features such as growth performance, feed efficiency, digestibility and meat quality.
