Dried citrus pulp (DCP) as a by-product from juice extraction of citrus fruit can be used as a feedstuff for ruminant animals (Belbaskis and Tsirgogianni, 1996). The DCP is composed of peel, inside portions, and culled fruits of the citrus family (e.g., orange, lemons, and grapefruit). The DCP is a pectin-rich bulky concentrate that is rich source of energy, fibre and calcium, but poor in CP and phosphorous. There is a different of opinion among researchers about the effect of DCP on milk yield, milk composition and blood metabolites components. The main objective of this experiment was to evaluated effects replacement of dried citrus pulp with barley grain on milk yield, milk composition and blood metabolites of dairy cows.

Pistachio hull (PH) is the main pistachio by-product produced from the pistachio dehulling process. The product consists of 12.7, 5.7, 16.6, 25, and 20% ash, EE, CP, NDF, and ADF, respectively and can be used as a feedstuff for ruminant animals. It is a mount of energy, fibre and potassium (Naserian and Vahmani, 2005). Because its constitutive tannin content can bind protein and cellulose, it was hypothesized that PH tannin can decrease the digestibility of protein. There is no clear consensus amongst researchers on the effect of dried pistachio by product on milk yield, milk composition, rumen fluid pH and N-NH3concenteration. The main objective of this experiment was to evaluate effects of different sources of supplemental protein with dried pistachio by product on milk yield, milk composition rumen fluid pH and N-NH3concenteration of dairy cows.

Lactating Dairy Cows

Cereal grains can provide the major source of energy in diets in order to meet the nutrient requirements of high producing dairy cows. However the amount of starch that can be included in the diets of dairy cows is limited particularly if starch is rapidly fermented such as barley starch. Reduction of feed intake, rumen pH, milk fat test, microbial growth and other metabolic disorders are expected if ruminally degradable starch is fed in amount that cant be efficiently metabolized by rumen microbs. Various techniques for processing barley grain have been developed to decrease the degradability of dry matter in rumen without reducing its extent of digestion. McNiven (1995) showed roasting of barley is more effective treatment. The objective of this experiment was to study of effects the roasting and ammoniation of barley grain on rumen pH, feces pH, milk yield and milk composition in dairy cows.

Actaplanin, a complex of glycopeptide antibiotics produced by Actinoplanes missouriensis, was investigated as a performance enhancer when incorporated in the diet of lactating dairy cows at the rate of 960 mglday. In a trial with autumn-calving cows over two successive lactations, the milk yield of animals given diets incorporating Actaplanin (no. = 132 lactations) showed only a small (proportionately +0·038), nonsignificant increase in milk yield over the controls (no. = 121 lactations). Overall, there were no significant differences in milk composition, cow body weight or condition score changes, mastitis cell counts or in the majority of blood metabolites.

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.

The aim of this research was to observe the effect of heat stress on milk yield and milk compositions of Holstein Friesian crossbred (HF) dairy cows. To fulfill the objectives, a total of 9 Holstein Friesian crossbred cows were selected for this study. Green grasses (German, Para) were supplied adlibitum and concentrate feeds (mixture of wheat bran, rice polish, mustard oil cake, di-calcium phosphate and salt) were supplied at the rate of 2.0 kg/day/cow. Management practices for all the cows were similar following the BAU Dairy farm practices. Data were collected on milk yield (l/h/d), relative humidity (%) and barn temperature (0C). The obtained temperature humidity index (THI) of July, August, September and October were 84.95, 81.99, 81.40 and 79.57, respectively. The highest THI was found in July which indicated higher heat stress during this month. A significant difference (p<0.05) in milk yield of cows was found among different months of July to October. The highest milk yield (6.10±0.50 l/h/d) was found in October among observed months. The compositions of milk such as total solids (TS), solids-not-fat (SNF), fat, protein, lactose, and ash also differed significantly (p<0.01). The highest values (%) of TS, SNF, fat, protein, lactose and ash content of milk were found in October as 12.63, 8.80, 3.83, 3.69, 4.39 and 0.72, respectively and lowest values (%) were in July as 12.20, 8.50, 3.71, 3.50, 4.30 and 0.69, respectively due to the high THI value. From these results, it is concluded that heat stress has strong effect on milk yield and milk composition of HF cows in Bangladesh. Management strategies are needed to minimize heat stress and attain optimal dairy animal performance.Asian J. Med. Biol. Res. June 2016, 2(2): 190-195
