ABSTRACT We aimed to evaluate the lactation curves, composition, and fatty acid profile of milk of lactating goats fed diets containing detoxified castor cake (DCC) by alkaline solutions during 150 days of lactation. Twenty-four Saanen and Anglo Nubian goats, approximately 17 months old (first lactation) and 43±2.97 kg body weight, were distributed in a completely randomized block design with eight replicates. Treatments consisted of three diets, one containing soybean meal (SM) and two others containing DCC, with calcium hydroxide [Ca(OH)2] […]

ABSTRACT The objective was to evaluate the intake, digestibility, nitrogen balance, and metabolic profile of lactating goats fed diets containing detoxified castor cake (DCC) by alkaline solutions during 150 days of lactation. Twenty-four Saanen and Anglo Nubian goats, approximately 17 months old (first lactation) and body weights of 43±2.97 kg, were distributed in a completely randomized block design with eight replicates. Treatments consisted of three diets, one containing soybean meal (SM) and two others containing DCC, with calcium hydroxide [Ca(OH)2] […]

The objective of the study was to investigate milk yield and eating behaviour of crossbred goats, German Improved Fawn × Hair crossbred (GIF) and Saanen × Hair goats (S), in subtropical eastern Mediterranean climate of Turkey during early summer season. Eight GIF and eight S goats were individually housed in 1.5 × 1.5 m pens. Diurnal eating patterns were monitored by a system that recorded meal size and meal length. Milk yield (kg/day) was 1.77 in GIF and 2.0 in […]

The objective of this study was to determine the fluctuation of serum antibodies in goats in the period before and immediately after kidding and the passive immunity acquisition efficiency in kids fed bovine and goat colostrum, to assess an alternative for colostrum management. Eighteen goats and their offspring were used in a total of 33 animals. Goat blood samples started to be collected 45 days before the predicated kidding date, at five-day intervals until the 5th day post kidding. The […]

Three different regions of the alphas1-casein gene (CSN1S1) were investigated to determine the frequencies of major alleles for null, low, intermediate and high milk protein expression in a herd of dairy goats raised in the southeastern region of Brazil. Genomic DNA samples were obtained from leukocytes of 145 dairy goats and regions of interest in the gene were amplified through Polymerase Chain Reaction (PCR), then evaluated in both agarose (O and E allele) and polyacrylamide gels (F allele). For better […]

The objectives of this experiment were to determine the apparent absorption, to estimate the endogenous fecal losses and the true absorption of Mg and to determine the ad libitum drinking water ingestion and the Mg serum concentration for Anglonubian (AN) and Saanen (SN) goat breeds. Twelve kids, six of each breed, with average 19.8 kg LW, were used. Semipurified diets (low Mg content) based on cracked rice, corn gluten meal and cellulose were supplemented with MgO to obtain the levels […]
