A study was carried out to evaluate the effect of single cell protein (SCP) supplement as a protein source on nutrient intake, digestibility, nitrogen balance and in situ digestion kinetics in four Nili Ravi buffalo bulls. Four iso-caloric and iso-nitrogenous concentrates containing 3, 6, 9 and 12% of Saccharomyces cerevisiae-fermented citrus pulp were formulated. All animals were fed a ration with a concentrate/forage ratio of 50:50. Diets were provided ad libitum twice a day as a total mixed ration in a 4 × 4 Latin Square Design. Each experimental period lasted 3 weeks while the overall study 12 weeks. The first 2 weeks of each experimental period were used as adaptation period while the third week as collection period. Chemical composition of fermented citrus pulp appeared as an excellent source of protein. No significant difference was observed on dry matter intake, digestibility of nutrients and SCP among all the treatments. Moreover, no significant effect was observed on ruminal pH and ammonia nitrogen at different times. Rate of disappearance and lag time of in situ dry matter digestion kinetics remained nonsignificant regardless of SCP percentage. Based on results of similar nutrients intake, nutrient digestibility, and ruminal parameters it is concluded that SCP could be used in the concentrate diet of ruminant up to 12%. Furthermore, the SCP has the potential of an alternative protein source in animal diet formulation.

ABSTRACT: The aim of this study was to evaluate the effect of total replacement of raw whole soybean (RAW) for roastedwhole soybean (ROS) on the production performance of Holstein cows. Two experiments were carried out usinga simple reversal design where RAW has been completely replaced by ROS. In experiment 1, 22 cows (175±60 days in milk)were used, and the dietary inclusion level of RAW or ROS was 3.7% of dry matter (DM). In experiment 2, 16 cows (130±50 days in milk)were used, and thedietary inclusion level of RAW or ROS was 11% of DM. In both experiments, ROS increased milk production by 1.1kgday-1 without changing fat and protein production. Dry matter intake or milk urea nitrogenwere not affected by dietary soy source. In experiment 2, plasma glucose concentration was decreased, and allantoin/creatinine ratio in urine tended to decreasein ROS. Experiment 2 also evaluated the nutrient digestibility and ruminal degradation kinetics of crude protein in two soybean sources. Roasting had no effect on the digestibility of DM, organic matter, and neutral detergent fiber. Roasted whole soybean hadgreater fraction B and lower protein degradation rate than did RAW; this showed that heat treatment was effective in increasing therumen undegradable amino acid flowto the animal, which suggesteda potential mechanism of action for improved performance observed in ROS.

Background: Subclinical ketosis (SCK) in dairy cows is a common metabolic disorder and a strong determinant of the health and performance of cows throughout lactation. Considerable amount of milk loss takes place with SCK incidence in dairy animals. Greater benefits are to be gained by monitoring the cows for SCK. The current study was aimed to find out incidence of SCK by urine test strip (Keto-Diastix). Methods: The present investigation was carried out on crossbred and Sahiwal cows and Murrah buffaloes (n=180) of the institute herd and rural dairy farms (n=97) around Karnal. The urine samples were tested for subclinical ketosis (SCK) 5-60 days postpartum from August 2019 to March 2020. Meteriological data on wet and dry bulb temperature and ambient temperature was collected and THI was calculated. Data of SCK incidence was classified based on stages of early lactation (5-20, 21-40 and 41-60d), parity (I, II, III and above), seasons (hot-humid, autumn, winter and spring) and milk production level ( less than 10kg, 10-20 kg and greater than 20 kg/d). Milk yield and environment variables were recorded during the experiment. Urine ketone and glucose level was detected by keto-Diastix to find out incidence of SCK. Result: Mean level of ketone bodies in urine was higher (P less than 0.01) in high yielding cows as compared to the medium yielders; however it did not vary in buffaloes. Ketone bodies in urine were high (P less than 0.01) in crossbred cows than that of buffaloes and Sahiwal cows. Urine glucose level did not vary among cows and buffaloes. It is concluded that high producing crossbred cows are more vulnerable to SCK between 41-60d of lactation and in III parity and above due to peak milk production. Sahiwal cows and buffaloes suffer less from SCK probably due to medium level of milk production. Factors like high milk yield, higher parity and hot-humid stress makes the animal more vulnerable to SCK. The screening of urine samples of animals at monthly intervals may be practiced by the farmers to monitor the incidence of SCK.

Lactating Cows

The aim of this study was to determine the best level of utilization of dried waste of cassava starch extraction (WCSEd) as a substitute for corn for lactating cows. Four lactating cows were fed diets with increasing levels (0%, 33%, 66% and 100%) of WCSEd as a substitute for corn. The intake and digestibility of dry matter and nutrients, milk production and composition, blood parameters of glucose and urea and microbial synthesis of the diets were evaluated. There was a reduction in dry matter intake, organic matter, ether extract and total carbohydrate, and increased intake of acid detergent fiber. Nutrient digestibility was not affected while the synthesis of microbial protein increased. These changes resulted in reduced milk production, without altering the efficiency of production or the constituents of milk, with a decreasing effect on daily production of lactose, solids and minerals. Metabolic parameters, glucose and urea nitrogen in plasma, remained within appropriate levels. The dried residue from the extraction of cassava starch can be used as feed for dairy cows to replace up to 100% of the corn ration. However, its use promotes a reduction in intake of dry matter and nutrients as well as a reduction in the production of milk, with impacts on the profitability of the product.
