Supplemental phosphorus can be completely replaced with microbial phytase in White Leghorn layer diets.

1. A study was conducted to assess the possibility of totally replacing supplemental phosphorus sources in White Leghorn (WL) layer diets (aged 28 to 45 weeks of age) with microbial phytase supplementation. One thousand commercial layers (HyLine White) of 28 weeks of age were housed in California cages fitted in open-sided poultry shed at the rate of 20 layers in each replicate.

Higher concentrations of folic acid reduced the dietary requirements of supplemental methionine for commercial broilers.

Objective: An experiment was conducted to study the effect of supplementing DL methionine (DL Met) at graded concentrations on performance, carcass variables, immune responses and antioxidant variables in broiler chicken fed folic acid (FA) fortified (4 mg/kg) lowmethionine diet.

Methods: A basal diet (BD) without supplemental DL Met, but with higher level (4 mg/kg) of FA and a control diet (CD) with the recommended concentration of methionine (Met) were prepared. The BD was supplemented with DL Met at graded concentrations (0%, 10%, 20%, 30%, 40%, and 50% supplemental DL Met of CD).

Oncocytoma of the parotid gland: A rare benign tumour.

Oncocytomas are one of the infrequent neoplasms seen in the oral cavity accounting for less than 2% of all neoplasms in the oral cavity with less than 1% chance of malignant transformation. They affect the major salivary glands and have a female predilection. The cognisance of the unique clinical and histopathological features is very important to conclude a confirmatory diagnosis.

Supplementation of sulfur and folic acid improves performance of broiler chicken fed suboptimal concentrations of dietary methionine.

Background: Supplementation of sulfur (S) and folic acid (FA) are known to spare the dietary requirement of methionine (Met) in chicken. An experiment was conducted to determine the effects of feeding graded concentrations of FA (0, 2, 4, 6, 8 mg kg ) and two concentrations of S (0 and 2 g kg ) in 5 × 2 factorial design. Diet without FA and S was considered as negative control (NC).

Effect of incremental levels of dietary total sulfur amino acids on performance of white leghorn laying hens fed diets containing guar (Cyamopsis tetragonoloba) meal.

Background: The present study evaluated the potential of increasing dietary levels of the most limiting amino acids such as total sulfur amino acids (TSAA) with respect to mitigating the adverse effects of the inclusion of guar meal (GM) in the diet of WL layers on egg production, feed efficiency and egg weight. In total, 4928 WL (Lohmann L) hens (32 week of age) were randomly allotted to eight treatments with seven replicates of 88 birds. The dietary treatments were a set of four maize-soybean meal based diets containing four graded concentrations of TSAA (5.

Effect of feeding higher concentrations of limiting amino acids on performance, slaughter variables and nitrogen retention in broiler chicken fed graded levels of toasted guar (Cyamopsis tetragonoloba) meal.

1. An experiment was conducted to study the effect of supplementing higher concentrations (100% vs. 110%) of critical amino acids (CAA) on performance (body weight gain - BWG, feed efficiency - FE), slaughter variables and nitrogen retention in broiler chicken (1-6 weeks of age) fed graded levels of toasted guar meal (TGM) as a protein source in diets.

Effect of supplementing germinated sprouts of pulses on performance, carcass variables, immune and oxidative stress indicators in broiler chickens reared during tropical summer season.

An experiment was conducted to study the effects of supplementing sprouts of pulses on performance, carcass variables, immune responses, and anti-oxidant variables in broiler chicken (day 1 to 6 weeks of age) reared during summer season in tropical region. Sprouts of black gram (BG, Vigna mungo), green gram (GG, Vigna radiata), and wild gram (WG, Vigna trilobata) were produced by soaking the pulses in water for 16 h and incubating at 37 °C for 24 h. Total phenolic content in sprouts of WG, BG, and GG was 102, 96.

Effect of different concentrations of metabolisable energy and protein on performance of White Leghorn layers in a tropical climate.

1. An experiment was conducted to study the effects of feeding graded concentrations of metabolisable energy (ME) and crude protein (CP) on the performance of layers. Nine diets with three concentrations each of ME (10.
