Feasibility of replacing fish oil with sunflower oil on the growth, body composition, fatty acid profile, antioxidant activity, stress response, and blood biomarkers of Labeo rohita.

A 90-day study was conducted to investigate the effects of substituting sunflower oil (SFO) for fish oil (FO) on various parameters in Labeo rohita (initial weight 18.21 ± 0.22 g).

Effect of once-a-day milk feeding on behavior and growth performance of pre-weaning calves.

Objective: The objectives of the present study were to evaluate the effects of once-a-day milk feeding on growth performance and routine behavior of preweaning dairy calves.

Methods: At 22nd day of age, twenty-four Holstein calves were randomly assigned to one of two treatment groups (n = 12/treatment) based on milk feeding frequency (MF): i) 3 L of milk feeding two times a day; ii) 6 L of milk feeding once a day. The milk feeding amount was reduced to half for all calves between 56 and 60 days of age and weaning was done at 60 days of age.

Effects of peripartal glucose precursor supplementation on lactation performance and metabolic health of primiparous and multiparous dairy cows.

Objective: Hyperketonemia remains a major metabolic issue of serious milk production and a major health concern in early lactation cows. Oral supplementation of glucose precursors (GP) can be used to prevent hyperketonemia in dairy cows. The objective of this study was to compare the beneficial effects of orally supplementing a mixture of GP on metabolic health indicators and milk production status of primiparous (PP) and multiparous (MP) dairy cows.

Nitrogen balance, production performance, and plasma metabolites of lactating buffaloes in response to varying dietary protein levels.

Protein imbalance in dairy rations affects N balance and milk N efficiency (MNE) resulting in extra N excretion to the environment. The objective of this study was to investigate the changes in N balance, milk production, and plasma metabolites of lactating buffaloes in response to different dietary crude protein (CP) supplies. Six multiparous Nili Ravi buffaloes in mid-lactation were used in this experiment in a 3 × 3 Latin square design.

Effect of feeding calcium propionate supplemented cotton seed cake on milk yield, milk composition and aflatoxin concentration in lactating buffaloes.

The objective of the current study was to reduce aflatoxin in a cotton seed cake (csc)-based diet and to decrease M level in milk by treating it with increasing levels of calcium propionate. Sixteen multiparous Nili-Ravi buffaloes were allocated to one of four treatments in a replicated 4 × 4 Latin square design. The treatments were calcium propionate treatment on csc at 0, 0.

Effect of photoperiodicity and methods of follicular wave emergence on follicle turn-over, recovery and quality of oocytes, and early in-vitro developmental competence of embryos using ovum pick-up in Nili-Ravi buffaloes: Preliminary evidence.

The objectives of the present study were to evaluate the effects of photoperiodicity, gauge (G) of ovum pick-up (OPU) needle, and two methods of follicular wave emergence on follicular turn-over, oocyte recovery (OR), quality of the oocytes (OQ), and early in-vitro developmental competence of embryos in Nili-Ravi buffaloes (n = 20). In 1 experiment, buffaloes (n = 12; 4 buffaloes/season) were randomly assigned to optimize the OPU's (n) either with 17 G or 18 G needle in one of the following seasons: 1) peak breeding season (PBS; Sep-Nov; n = 31), 2) transition breeding season (TBS; Dec-Feb; n = 32), and 3) low breeding season (LBS; Apr-June; n = 32). During 2 experiment, buffaloes (n = 8) were enrolled randomly in a 2 × 2 cross-over design to compare the two methods of wave emergence either using follicular ablation (FA; n = 4), or synchronization protocol (CIDR-EB; n = 4) during PBS.

Effect of increasing pre-pubertal concentrate levels on reproductive and lactation performance of Nili-Ravi Buffalo heifers.

The objective of this study was to determine the effect of increasing total nutrient supply by increasing level of concentrate supplementation in forage-based diet of growing Nili-Ravi buffalo replacement heifers on pre-pubertal growth rate and its impact on age at puberty and post-pubertal productive and reproductive performance. Twenty-eight Nili-Ravi buffalo heifers of 7 ± 1 month age were divided into 3 groups. The treatments were 3 levels of concentrate (crude protein (CP) = 17.

Effects of increasing dietary protein supplies on milk yield, milk composition, and nitrogen use efficiency in lactating buffalo.

Nitrogen efficiency of lactating buffalo can be increased by providing dietary crude protein (CP) precisely to the requirement. Twelve lactating Nili-Ravi buffaloes (6 primiparous and 6 multiparous) at 76 ± 37.5 days in milk (DIM) were used in this study.

Effect of increasing dietary metabolizable protein on nitrogen efficiency in Holstein dairy cows.

Objective: The objective of the study was to determine the effects of increasing levels of metabolizable protein (MP) on lactation performance and nitrogen (N) efficiencies in lactating dairy cows.

Methods: Nine multiparous cows in mid lactation [113±25 days in milk] received three treatments in a 3×3 Latin square design with a period length of 21 days. The treatments were three diets, designed to provide similar energy and increasing supply of MP (g/d) (2,371 [low], 2,561 [medium], and 2,711 [high] with corresponding crude protein levels [%]) 15.
