Kid Growth Comparison between Murciano-Granadina and Crossbred Murciano-Granadina×Boer in a Mixed Rearing System

Abstract

In dairy goats, the low average daily gain and the high conversion ratio for milk and concentrate of the kids mean that their sale price does not offset the costs generated. The hypothesis proposes that a crossbreeding of the Murciano-Granadina breed (MG) with the Boer breed (MG×Boer) will improve the profitability of the kids sold. Thus, the effect of two different groups of kids (purebred MG and crossbred MG×Boer) on birth weight (BW), mortality, average daily gain (ADG), the time for minimum slaughter weight (7 kg) and its variation factors were studied. MG×Boer kids had a 27% greater BW than purebred MG kids (2885 ± 84 g and 2275 ± 74 g, respectively), similar ADG (156 ± 6 g and 142 ± 6 g, respectively) and mortality (18% and 20%, respectively), and reached minimum slaughter weight a week sooner. ADG was less and less as the lactation period progressed due to a lower milk consumption and milk energy value, which highlights the importance of providing a concentrate that will compensate for this reduced energy content. In conclusion, the results show that MG×Boer crossbred kids reached the minimum slaughter weight a week earlier than purebred MG kids, and highlighted the improvement of farm profitability through the increase of milk sold and the need to provide a concentrate feed to enhance the growth of the kids.

Breeding strategy and contract farming model to promote Boer Cross population continuity: A case study at Sadhana Arif Nusa Company Lombok Island West Nusa Tenggara Province, Indonesia)

“…Thus, according to [18], the existence of contract farming can provide various benefits for the parties involved, especially for breeders, namely obtaining consulting services on production methods, obtaining funds for capital, and obtaining new technology so that farmers gain new knowledge, and can minimize price risk and as a support for the opening of new markets. In addition, farmers who participate in contract farming's will generally have a higher level of profit than independent farmers who do not participate in contract farming's [18]. However, in some cases, it can also give the opposite result; namely, non-partner farmers are higher in profit than partner farmers [19].…”

“…Therefore, SAN-C began to pioneer a planned and centralized breeding process at the Breeding Center in Tiu Borok, East Lombok Regency. Several researchers reported that ennobled local goats with Boer goats were proven to increase the productivity of their crosses [7,9,17,18]. Zaenuri et al [7], reported that from 20 nannies 18 of them gave birth to 34 heads consisting of 6 single males, 12 single females, 8 male twins, 2 female twins and 6 male-female twins.…”
