Preovulatory follicular dynamics and ovulatory events following the use of GnRH 84 h after medroxyprogesterone acetate sponge removal in postpartum buffaloes.

Herein, we evaluated the effects of gonadotropin hormone-releasing hormone (GnRH) administration 84 h after medroxyprogesterone acetate (MAP) sponge removal on follicular growth, ovulation timing, and pregnancy per artificial insemination (AI) in cosynchronized postpartum Nili Ravi buffaloes. In this study, 58 Nili Ravi postpartum buffaloes (DIM = 103 ± 1.64) were randomly divided into two treatment groups (n = 29/treatment): GnRH-TAI-84 and TAI-84.

Insect Larvae as an Alternate Protein Source in Poultry Feed Improve the Performance and Meat Quality of Broilers.

The primary challenge facing the global animal industry is the scarcity of protein feed resources. Various insects are gaining prominence as innovative feed sources due to their economic, environmentally friendly, and nutritious attributes. The purpose of the present study was to determine the effects of a partial replacement of soybean meal with fall armyworm (Lepidoptera: Noctuidae) and black soldier fly (Diptera: Stratiomyidae) on the growth performances, blood parameters, gut histology, and meat quality of broilers.

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.

The effect of GnRH administration/insemination time on follicular growth rate, ovulation intervals, and conception rate of Nili Ravi buffalo heifers in 7 -day-CIDR Co-synch.

The present study aimed to compare two different insemination times (72 vs 84 h) associated with an ovulation induction (GnRH) in a 7-day CIDR Co-synch to improve the conception rate of Nili Ravi buffalo heifers. Forty Nili Ravi buffalo heifers were randomly separated into two treatments based on artificial insemination (AI) timing (72 vs 84 h). All heifers were subjected to controlled internal drug release (CIDR), containing 1.
