“…Black Bengal breed is considered an excellent breed for the various reproductive attributes such as high litter size and early maturity (28). Haldar et al (29) have also recently reported 68.39% multiple births in Black Bengal goats, of which 61.70% were twins. High incidence of twin births (56.3%) has been reported in Black Bengal goats in the neighboring country Bangladesh (30).…”

“…Breed-wise and parity-wise least squares means of litter size for different genotypes at A959C, G1189A, and C818T loci of GDF9 gene. Haldar et al (29) who concluded that larger litter size was strongly influenced by higher parity and higher previous litter size in these goats. Similar findings have also been reported in Damascus goats and crossbred native goats in north Mexico (35,36).…”

Goats form the backbone of rural livelihood and financial security systems in India but their population is showing decreasing trend. Improvement of reproductive traits such as prolificacy offers a solution to stabilize the decreasing goat population and to meet the nutritional needs of growing human population. In the present study, six novel SNPs in three candidate genes for prolificacy (BMPR1B, BMP15, and GDF9) were genotyped in seven breeds of Indian goats to evaluate their association with litter size. Tetra primer ARMS-PCR and PCR-RFLP based protocols were developed for genotyping six novel SNPs, namely, T(-242)C in BMPR1B; G735A and C808G in BMP15; and C818T, A959C, and G1189A in GDF9 gene. The effect of breed was highly significant (p ≤ 0.01) on litter size but the effect of genotype was nonsignificant. The effect of parity on litter size was also significant in the prolific Black Bengal breed. The litter size differences observed between breeds are attributed to breed differences. Novel mutations observed at different loci in GDF9, BMP15, and BMPR1B genes do not contribute to the reproductive capability of the investigated breeds. Further studies with more number of breeds and animals exploring association of these novel SNPs with reproductive traits may be fruitful.

“…In Merino sheep, it was reported that BW is associated with the traits of MUSWT, LMYP, bone weight in carcass (BONE_WT), carcass bone percentage (BONEP), and FATP [36]. In Black Bengal goats, there is a positive relationship between withers height (WH), distance between tuber coxae bones (DTC), BW, and litter size, while physical strength was implicated in an increased likelihood of multiple births in goats bearing multiple fetuses from those bearing a single fetus [59].…”

The Pelibuey sheep has adaptability to climatic variations, resistance to parasites, and good maternal ability, whereas some ewes present multiple births, which increases the litter size in farm sheep. The litter size in some wool sheep breeds is associated with the presence of mutations, mainly in the family of the transforming growth factor β (TGF-β) genes. To explore genetic mechanisms underlying the variation in litter size, we conducted a genome-wide association study in two groups of Pelibuey sheep (multiparous sheep with two lambs per birth vs. uniparous sheep with a single lamb at birth) using the OvineSNP50 BeadChip. We identified a total of 57 putative SNPs markers (p < 3.0 × 10−3, Bonferroni correction). The candidate genes that may be associated with litter size in Pelibuey sheep are CLSTN2, MTMR2, DLG1, CGA, ABCG5, TRPM6, and HTR1E. Genomic regions were also identified that contain three quantitative trait loci (QTLs) for aseasonal reproduction (ASREP), milk yield (MY), and body weight (BW). These results allowed us to identify SNPs associated with genes that could be involved in the reproductive process related to prolificacy.

“…Body size and shape measured objectively could improve selection for growth by enabling the breeder to recognize early maturing and late maturing animals of different sizes (Akpa et al, 2013). Where genetic evaluation has still limited use, identification of some descriptive linear traits may be useful and farmers' friendly tools for selecting goats with desirable characters (Haldar et al, 2014).…”

The purpose of this study was to evaluate present level of productivity and determine linear body traits of Alpine goats raised in Serbia on smallholder farms. Data were collected from 22 smallholder farms located in Belgrade district, with total of 330 purebred Alpine does 2-9 years of age, 145 yearling does and 476 kids. Traits measured were: body weight of does, body weight of kids at birth, 30 days of age and at weaning (90-120 days), prolificacy of mature and yearling (primiparous) does, six linear body traits of does (wither height, body length, hearth girth, chest depth, chest width, pelvic width) and milk production (milk yield, milk fat and milk protein content). The analysis showed the average body weight of does to be 54.96 kg, while the average body weight of kids at birth, 30 days of age and weaning was 2.73 kg, 8.7 kg and 18.3 kg., respectively. Prolificacy was 144% in mature and 125% in yearling does. Measurements of linear body traits were: wither height 67.87 cm, body length 71.92 cm, hearth girth 81.79 cm, chest depth 32.93, chest width 21.49 cm and pelvic width 17.63 cm. Among dairy production traits, following results were obtained: lactation length 220.73 days, total milk yield 531.66 kg, milk fat content 3.33% and milk protein content 3.16%. It was concluded that the overall productivity of Alpine goats raised under smallholder production systems in Serbia is satisfying. Giving the fact that these animals are usually kept under poor conditions, many of these productive traits are very good.
