Severe feather pecking (SFP) in commercial laying hens is a maladaptive behavior which is associated with anxiety traits. Many experimental studies have shown that stress in the parents can affect anxiety in the offspring, but until now these effects have been neglected in addressing the problem of SFP in commercially kept laying hens. We therefore studied whether parental stock (PS) affected t...

Background: Moringa oleifera seed meal is a potential noble feed ingredient that could be incorporated into the diet of poultry. It cheaper alternative considering its ability to thrive under all climatic conditions in Nigeria, West Africa. The study was aimed at evaluating effects dietary inclusion (MOSM) on egg characteristics, conversion ratio and body weight parameters Yoruba Ecotype Nigeri...

a study was carried out to evaluate the secondary sexual characteristics of four strains of cocks, comprising of two (2) exotics; bovan nera black (bnb) and isa brown (isb), one (1) improved local strain, shika brown (sb) and one (1) unimproved local strain, normal feathered cock (nfc). a total of 64 birds (16 for each strain) at 36, 38, 40 and 42 weeks were used for the study. the result indic...

This study aimed to investigate plumage conditions, injuries in the comb, cloaca, and feet at end of laying period (73 weeks age) native Atak‐S (A‐S) foreign Isa Brown (IB) Novogen White (NW) genotypes reared two different cage densities. A total 480 hens, including 160 each hybrid, were used present study. Each hybrid group was divided into subgroups containing eight (468.75 cm2/hen) 12 animal...

This study aims to determine the use of probiotics Lactococcus lactis and Lactobacillus casei. on analysis laying hens infected with Escherichia coli. A total 120 aged 25 weeks were divided into 6 treatments. Each treatment included 4 repetitions, each which 5 hens. The treatments factor a, namely infectious non-infectious escherichia coli B, AGP, basal feed probiotics.. result this research sh...

conditions throughout the test. The hens were provided nutrients to meet the needs of all the hens based upon compilation of the breeder recommendations. The eggs from these strains were collected every 28 days from the previous 24 hrs production. Once collected the quality and compositional properties of the eggs such as pH, solids, whipping height, Haugh units and angel food cakes were evalua...

Step-Up Protein (SUP) rearing regimens can reduce Feed Consumption (FC) and Body Weight (BW), while still resulting in pullets with equal or superior egg production and egg mass to pullets grown on a Step-Down Protein (SDP) program. Egg weight has been reduced due to SUP programs, presumably due to the reduced BW at sexual maturity. Because BW is reduced by SUP regimens and a slight lowering of...

This study aimed to examine the nutrient utilization of rump round meat and lotus root using young (32 wk) and aged hens (108 wk) as an animal model. Rump round meat and lotus root were prepared with or without enzymatic treatment. For each age group of laying hens, a total of 24 Hy-Line Brown laying hens were randomly allotted to one of two dietary treatments with six replicates. For rump roun...
