Stage Of Lactation

Milk is an important elements due to its high nutritious and balanced in human diet. In Asian, goat milk is the most consumed because of the unique taste, more nutritious than cow milk. However, milk production and composition values differ at every stage of lactation in goats. Thus, determining the highest milk production and producing the best quality goat milk is essential to satisfy the local market demands. The objective of the present study is to determine the milk yield and milk composition at different lactation stages and to evaluate the lactation curves in Saanen goats. The lactation stages can be categorized into three, early (less than 80 days), mid (80 – 140 days) and late (over 140 days) days in milk (DIM). In total, 90 milk samples were collected from 15 goats representing early (n=5), mid (n=5), and late (n=5) stages of lactation. The Saanen goats were raised under the same conditions, and milking was done early in the morning (9.00am).The milk yield from Saanen goats were collected and measured weekly at each stage of lactation. Milk samples were analyzed for fat, protein, solid non-fat, and lactose. Current result illustrated, there were significant different (p ˂ 0.05) among three stages of lactation in milk yield, solid non-fat, fat, protein and lactose. In terms of food regulation, the Saanen goats almost fully met the standard requirements for milk production and composition. In addition, this study also observes the lactation curves in Saanen goats and analyse the curve shapes and patterns. The average milk yields from three different stages develops a concave downward curve. The results indicated that mid yield increased from early to mid- lactation and decreased thereafter until the end of lactation.

Casein Synthesis

A study was carried out to analyse the production and composition of milk from Malagueña goats of different genotypes for the content of αs1-casein. Twenty goats were used, half of them with a high (HG) and half with a low (LG) genetic capability for αs1-casein synthesis. Among the ten HG goats, seven had BB and three had AB genotypes, whereas there were seven EF and three FF genotypes among the LG goats. The goats were fed a diet differing in crude protein content, 136 and 177 g/kg dry matter for diet 1 (D1) and diet 2 (D2), respectively. For each genotype group, a trial was conducted, with each of the two diets in a two-period balanced change-over design, in which the milk production and composition were analysed. The genotype was found to determine milk composition, with that produced by the HG goats being higher in total solids, protein, αs1-casein, αs2-casein and fat. Analysis of milk production values and, especially, those of the yields of the different components, revealed an interaction between the factors. HG goats that consumed D1 were more productive than LG goats, but this ceased to be so when the D1 diet was replaced by D2. However, LG goats, although less productive than HG ones when the D1 diet was consumed, showed increased productive capacity when D1 was replaced by D2. The main difference for the fatty acid profile of the dairy fat is that the milk fat produced by the HG goats contained higher levels of short and medium-chain fatty acids. From these results, it is concluded that, in terms of favouring production, the advantage of replacing animals with a low capacity for αs1-casein synthesis with those of a high capacity seems to depend on the protein level in the diet. Similarly, the advantage of changing to a diet of higher protein content depended on the animal's genotype.

Effect Of Feeding

The study was conducted to evaluate the effect of feeding herbal galactogogue preparation (Sanjivani biokseera) on the milk yield and milk constituents in lactating Kankrej cows. Thirty-two lactating Kankrej cows in their 1st to 6th lactation were taken for the experiment from 3 days after calving up to 52 days postpartum. All the animals were fed as per the standard seasonally available roughages and concentrates to meet their nutritional requirements. The cows were randomly divided into two uniform groups of 16 cows in each according to initial milk yield and milk composition. The animals in group-I were not given any supplement and served as control. The animals in group-II were given Sanjivani biokseera (Naturewell Industries) @ 60 g per day for 1-month, commencing 3 days after calving, in addition to the usual feeds/fodders. A clear difference was observed in milk yield from day 8 onward of experiment between groups with significant (plessthan0 0.05) higher values from day 16-52 in cows fed herbal galactogogue as compared to control, but no such distinct effect on milk constituents was observed on day 52 when analyzed. The use of herbal galactogogue significantly (p lessthan 0.05) increased the overall average of 52 days milk production, which was 9.34 ± 0.21 lit/day in supplemented as compared to 7.75 ± 0.26 lit/day in control animals. It was concluded that herbal galactogogue (Sanjivani biokseera) could increase milk yield in lactating dairy cows through its galactopoetic property and improved rumen environment.
