To compare the relative value of the fish meal and the cottonseed meal in highly fermentable diets (40% forage and 60% concentrate with), eight cows were assigned randomly to diets with 0, 1.5, 3 and 4.5 percent of the fish meal. In the first experiment, the degradability of dry matter and crude protein of the fish meal, the cottonseed meal and concentrate in diets was estimated with different ...
Excess nitrogen excretion, ammonia and odour are environmental pollutants associated with pig production. Reducing dietary crude protein (CP) will lower the amount of excreted, reducing potential for emissions, if diets adequately formulated to supply amino acids production performance is maintained. Crude content in finishing pigs has been lowered recently, but quantitative effect this reducti...
Polysaccharides were extracted from eight kinds of Chinese mushrooms using three solvents and were evaluated for their total carbohydrate, polyphenolic and protein contents, and antioxidant and anti-proliferation activities. The results suggested that all the polysaccharides had significant antioxidant capacities (EC(50) ranged from 1.70 ± 0.42 to 65.98 ± 1.74 μM TE/g crude polysaccharide inhib...
A 70-day experiment was carried out to evaluate biofloc system operation with no carbon addition by manipulating dietary protein and lipid levels for Nile tilapia (Oreochromis niloticus) cultivation. Three treatments were conducted; Control treatment (C; fed on a 30% crude [CP] diet supplemented 3% vegetable oil [VO] + of external source [ECS] in rearing tank), low protein–low (LPLL; 23% CP (VO...
To evaluate the effects of amount and profile amino acid (AA) on milk protein yield (MPY), mammary metabolism, efficiency nitrogen use (ENU), ten cows were used in 5 × replicated Latin squares fed a positive control (16.1% crude protein-CP) or two lower CP diets (14.6 13.2%) with without essential AA (EAA) infusion. The EAA solutions provided predicted limiting each treatment continuously infus...
A trial was conducted to determine the effect of low crude protein (CP) diets with constant metabolizable energy to crude protein (ME:CP) ratio on growth, body composition and nutrient utilization of broiler chicks from 1 to 26 days of age. Four dietary treatments having four levels of CP and ME as 23, 22, 21 and 20% and 3,036, 2,904, 2,772 and 2,640 kcal/kg, respectively, were formulated and a...
An experiment was conducted to determine apparent ileal digestibility of crude protein (CP) and amino acids (AA) and digestible CP and AA of fish meal (FM) in 21-d-old broiler chickens using the regression technique. Four diets containing 0, 1, 2, and 3% FM in place of cornstarch were formulated with FM as the sole contributor of CP and AAs in the sequential diets. Eighty 14-d-old broiler chick...
the study was carried out on 120 crossbred holstein × shahiwal dairy cows for a period of 150 days to quantify the influence of dietary energy and protein intake on yield and composition of milk. total 12 dairy farms having similar housing systems and holding at least 20 dairy cows in between mid to late lactation were selected for study purposes. the farms were located in the peri-urban and ur...
the aim followed in the present research was to study the effects of reduction in dietary crude protein on milk production and on blood components in lactating holstein dairy cows when in heat stress. a number of 63 holstein dairy cows (71 ± 16.5 dim) were chosen to be made use of in a randomized complete block design. the cows were randomly assigned to any one of the three experimental rations...
