“…Means of milk urea were similar to those by Bava et al (2001) for Saanen goats, with higher milk yield and lower milk protein content. However, the present data were lower than those by Sahoo & Walli (2008) for crossbred goats and by Cabiddu et al (1999) for Corsican goats fed exclusively pasture. The positive correlation of milk urea and milk yield in all the three levels indicated that urea recycling rate was irrespective of milk yield.…”

“…Indeed, protein can be produced in the rumen from urea and other nitrogen sources and the flow of urea is from the rumen to the blood and vice versa (Harmeyer & Martens 1980, Cunningham 2002. Plasma urea is positively correlated to milk urea in cows (Roseler et al 1993, Butler et al 1996, Broderick & Clayton 1997, sheep (Cannas et al 1998) and goats (Cabiddu et al 1999, Bava et al 2001, Sahoo & Walli 2008. Given that milk is easier to collect than blood, milk urea is a suitable parameter to evaluate urea metabolism, especially on a herd level (Schepers & Meijer 1998), both in intensive and extensive dairy farms.…”

The aim of this study was to investigate the relationships among milk urea, blood plasma urea, milk yield and body condition score (BCS) in primiparous goats fed at pasture. Ninety goats of Sarda breed were used and, on the basis of their yield level, divided in three groups of 30 animals each, low (LY), intermediate (IY) and high milk yield (HY). Daily milk yield, milk protein content, milk urea, plasma total protein and albumin, plasma urea and BCS were measured at monthly intervals from 45 days in milking (45 DIM) to 165 DIM. Milk yield level affected protein concentration of milk and plasma, whereas albumin showed no variation. Plasma and milk urea showed a high correlation (P<0.001) despite of the yield level; plasma urea was always lower than milk urea. BCS decreased on 75 DIM and again after 135 DIM, and it was not affected by the milk yield level. Because milk urea and plasma urea were closely correlated and not influenced by the yield level, the study pointed out that measurement of milk urea could be utilized to evaluate urea metabolism also for browsing goats.

“…For the fat parameter, there was no difference between the energy levels tested and also in relation to lactation time (Table 3), corroborating with other studies that evaluated milk fat (Zambom et al, 2005;Costa et al, 2008;Sahoo & Walli, 2008;Araújo et al, 2009). Morgan et al(2003) obtained from goats reared in France, but according to this same work, breed and breeding conditions can cause a variation in the milk fat content from 5.1 to 3.2%.…”

Similar results were found in Queiroga et al (2007), Sahoo and Walli (2008), Araújo et al (2009) and Silva et al (2013) who used different percentages of energy in the diet.

ABSTRACT. We evaluated the physical and chemical characteristics of raw milk from goats supplemented with levels of Total Digestible Nutrients (TDN) in the dry period. Samples from 20 goats were divided into 4 groups, 3 groups received 400g concentrate per animal with different levels of TDN (65, 75 and 85%), and the control group (without concentrate). Four samples of milk were used for each animal, in four sampling periods, which were subjected to physical and chemical analysis. There was no significant difference between the treatments for the parameters of acidity and fat. The diet without concentrate presented higher value for the cryoscopic index. Mean values of the four treatments were within the range set by the Brazilian legislation for all parameters evaluated. The use of concentrate, containing 85% TDN in goat supplementation, was favored the physical and chemical characteristics of the milk during the dry period.Keywords: concentrate, legislation, raw caprine milk.Características físico-químicas do leite de cabras suplementadas com diferentes teores de nutrientes digestíveis totais durante o período seco do ano RESUMO. Este trabalho teve por objetivo avaliar as características físico-químicas do leite de cabras suplementadas com teores de Nutrientes Digestíveis Totais (NDT) no período seco do ano. Foram utilizadas amostras de leite de 20 cabras as quais foram divididas em quatro grupos, sendo que três grupos receberam suplementação de 400 g de concentrado por animal com diferentes teores de NDT (65, 75 ou 85%) e o grupo controle que não recebeu concentrado. Foram utilizadas quatro amostras de leite para cada animal, em quatros períodos de coleta, as quais foram submetidas à análise físico-química de acidez titulável, crioscopia e gordura. Não houve diferença entre os tratamentos para os parâmetros de acidez e gordura. As amostras de leite dos animais que receberam a dieta sem concentrado apresentaram maior valor para o índice crioscópico. As médias das amostras dos quatro tratamentos estavam dentro dos parâmetros fixados pela legislação brasileira para todos os parâmetros avaliados. A utilização de concentrado contendo teor de 85% de NDT na suplementação de cabras favoreceu as características físico-químicas do leite durante o período seco.Palavras-chave: concentrado, legislação, leite cru caprino.

“…Tice et al (1993) andFathi Nasri et al (2007b) have seen a positive effect of feeding roasted soybean on milk yield of cows while Santos et al (1998) reported non encouraging results. Feeding of increased rumen undegradable protein or protected methionine has produced variable results (Alonso et al 2008;Sahoo and Walli 2008;Krishna Mohan and Reddy 2009;Yadav and Chaudhary 2010). Feeding of naturally occurring bypass protein to crossbred cows (Chaturvedi and Walli 2000), feeding of protected protein to crossbred cows (Bugalia et al 2008;Mondal and Chopra 2008), and in buffaloes (Chatterjee and Walli 2003) resulted in a significant increase in milk production.…”

An experiment was conducted to evaluate the effect of roasting whole soybean in the local level on their chemical composition, nitrogen fractions, in situ degradability, and feeding performance in crossbred (Karan Swiss and Karan Fries) dairy cows. Twelve lactating crossbred cattle (369.08 ± 17.53 kg body weight) were randomly divided into two groups on the basis of milk yield (10.18 kg/day) and day of calving (89 days) in a randomized block design. Cows were fed green maize fodder and concentrate mixtures with 1 kg raw soybean as fed basis (7.6% of total diet) in the control group, where as roasted soybean replaced raw soybean in the treatment group to make both diets isonitrogenous and isocaloric. The roughage to concentrate ratio was around 55:45 in both diets. The cows were housed in individual byres and fed experimental diet for 90 days. The total dry matter intake per animal in both groups was similar. The digestibility of dry matter, organic matter, crude protein, ether extract, and neutral detergent fiber was comparable in both groups. The average milk production and fat-corrected milk yield per day was similar during the trial. Milk fat, milk protein, and solids not fat content remained unaffected and similar in both groups. All the animals maintained their body weight in both groups. Thus, rumen bypassing of protein fractions at the present method of bypassing did not have the desired level of beneficial effect in medium producing crossbred cows.
