“…However, between the treatment groups milk fat percentage of group T 2 was significantly (P<0.05) higher than group T 1 .This effect on milk fat percentage may be due to more availability of fatty acids for absorption in intestine due to protection of fat and these fatty acids are directly ISSN: 2661-6270 (Print), ISSN: 2661-6289 (Online) DOI: https://doi.org/10.3126/janr.v2i1.26062 incorporated in milk fat after absorption from intestine, leading to increase in milk fat.

Bypass protein stimulates the voluntary feed intake, increase quality milk production and thereby improves the economic status of dairy cows farming. This study was conducted to assess the effect of supplementation of bypass protein on lactation performance of dairy cattle. The experiment was conducted by using 2 factorial completely randomized designs. Milk yield of individual animal was recorded daily and milk composition was recorded at fortnight interval. Results revealed that the average daily milk yield of cows fed with Heat treated soyabean cake-T1 (4.29 L) was greater than cows fed with formalin treated soyabean cake-T2 (3.56 L) followed by control group-T3 (2.62 L). . The fortnight average milk protein and fat percentages were 2.91, 2.94 and 3.18% and 5.52, 5.55 and 4.47% for T0, T1 and T2 groups respectively. The weekly average milk SNF and milk density were 8.12, 8.37 and 8.64 % and 25.67, 27.80 and 27.10%, for group T0, T1 and T2 respectively. Experiment revealed that by-pass protein supplementation to lactating animals is one of the option for improving the milk production and milk composition and suggested that further study should be conducted to precise the optimum level of bypass protein supplementation and to quantify the experimental period.

“…On the one hand, this concerns the protection of the environment of the rumen, and on the other it refers to fat security before hydrogenation. The protected fat can be obtained by various methods such as encapsulation and calcium salt formation of fatty acids (5,6), although Ca salts will be affected by a number of factors including ruminal pH and degree of unsaturation and chain length of the fatty acid.…”

Feed fats are commonly used as a component of high-yielding cow diet rations. Many studies have been conducted on the effects of fat supplementation on metabolism, milk composition, and improvements in dairy cow reproduction. The positive effects on fat (vegetable oil) and energy supplementation on improvements in reproduction are well documented. Consumption of polyunsaturated fatty acids (PUFAs), including n-3 acids, in appropriate feed doses improves fertility of dairy cows. A fat source with high levels of acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is marine oil, especially fish and algae. By modification of cow rations, EPA and DHA can be utilized to reduce synthesis of PGF 2α in the endometrium, which can prevent luteolysis of the corpus luteum during early pregnancy. The PUFAs also may have a direct impact on key genes and their proteins that regulate biochemical processes and pathways between the corpus luteum, the uterus, and the embryo. The effect of n-3 fatty acids on the survival of embryos is not yet clearly defined.

“…Interesting result was found in the present study; SOYXYL supplementation at 6% and 9% decreased (p<0.05) the concentration of sperm of Simmental bulls (Table 1). Earlier study by Shelke et al (2012) reported that dietary supplementation of rumen-protected protein improved efficiency of energy utilization in the ruminant.…”

The study aimed to evaluate the effect of SOYXYL as one of the dietary protected protein supplement product in the rations on the reproduction performance of Simmental bulls. Twelve 5 years-old Simmental bulls were allotted to 4 treatment groups with 3 replications in each, i.e.: T0= control ration (elephant grass + 5 kg/head/day commercial concentrate), T1= control ration + 150 g protected protein supplement SOYXYL (3% of concentrate), T2 = control ration + 300 g SOYXYL (6% of concentrate) and T3= control ration + 450 g SOYXYL (9% of concentrate). The experiment lasted for 90 days. At the end of the experiment, semen and blood were collected and body weight gain was measured. The variables measured included sperm motility, sperm concentration, blood protein, blood urea and the concentration of testosterone. Results showed that SOYXYL supplementation, particularly at the levels of 3 and 6%, increased the total plasma protein of bulls. SOYXYL supplementation at 3% from concentrate resulted in increased plasma urea concentration. Feeding SOYXYL, particularly at the levels of 6 and 9%, increased the average daily gain of bulls as compared to control. Feeding 3% SOYXYL increased, but at the levels of 6 and 9% decreased the concentration of sperm of bulls. The concentration of testosterone was higher in the bulls received 3 and 6% SOYXYL in the rations. Dietary supplementation of SOYXYL increased the sperm motility of Simmental bulls. In conclusion, dietary supplementation of SOYXYL at the level of 3% increased plasma protein, testosterone, and sperm concentrations as well as sperm motility. However, supplementation of SOYXYL at 6 and 9% from rations decreased the concentrations of sperm and testosterone.
