<h2>ABSTRACT</h2> Accurate identification of cows' likelihood conception during the period from recent calving to first artificial insemination (AI) will provide assistance in managing fertility dairy cows and contribute economic prosperity sustainability farm. The purpose this study was use FTIR spectroscopy collected predict cow's AI, or second AI. This specifically focused on role spectral farm data at different time windows improving accuracy model for predicting From 2019 2023,...
Abstract Background Probiotics and essential oils feed supplements are widely used in the aquaculture sector. This study was conducted to evaluate effects of dietary supplementation with probiotics, their combination on growth performance, serum biochemical parameters, antioxidant capacity, resistance against Aeromonas veronii , intestinal histomorphology Nile tilapia ( Oreochromis niloticus ). A total 360 O. fingerlings were randomly assigned four groups (3 replicates/ group; each replicate...
The current study was conducted to assess the impact of different LED light colors on welfare indicators in Muscovy ducks. These parameters encompassed growth performance, specific behaviors, tonic immobility (TI), feather score, haematological, and serum biochemical parameters. Eighty-four healthy unsexed ducklings aged two weeks were randomly assigned four groups (3replicates/group; each replicate contains 7 birds) based colors. first group raised under white light, second red third blue...
The effects of shearing on behavioral patterns, antioxidants, and inflammatory stress biomarkers was investigated in Ossimi sheep. Clinical parameters patterns were recorded, serum samples collected pre-shearing 1, 5, 10 15 days post-shearing from 60 results revealed that grooming standing idle frequencies significantly (P<0.01) increased post-shearing. There significant increases IL-6, cortisol, MDA detected the 1st to 10th day compared values. IL-2 TNF-α until 5th values, while decreases...
Milk composition always serves as an indicator for the cow’s health status and body condition. Some non-genetic factors such parity, days in milk (DIM), calving season, which obviously affect performance, therefore, need to be considered dairy farm management. However, only a few compositions are used current animal selection programs. The mid-infrared (MIR) spectroscopy can reflect global of milk, but this information is currently underused. objectives study were detect effect some on...
Introduction Melatonin is a neurohormone involving various biological processes, including restoration of cyclicity in animals with seasonal breeding patterns. The use melatonin different forms has gained broader acceptance species, particularly summer anestrous buffaloes. Objectives objective the current study was to evaluate effect on reproductive and productive performance crossbred buffaloes during low season. Methods Sixty-five cyclic reproductively sound were randomly allocated three...
Abstract Background Milk produced by dairy cows is a complex combination of many components, but the effect mastitis has only been investigated for few these components. mid‐infrared (MIR) spectra can reflect global composition milk, and this study aimed to detect relationships between milk MIR spectral wavenumbers somatic cell count (SCC)—a sensitive biomarker mastitis. Methods Pearson correlation analysis was used calculate coefficient score (SCS) wavenumbers. A general linear mixed model...
This study examined the sedative, analgesic, behavioral, and clinical effects of a combination xylazine (XY) nalbuphine-xylazine (NA-XY) in camels.A total five adult camels were used prospective randomized cross-over design with wash out period two weeks.Camels allocated randomly to treatment groups: XY group (xylazine, 1.1mL/100 kg IV) NA-XY IV nalbuphine, 1 mg/kg IV).The evaluated prior administration (baseline) at 5,15,30, 45, 60, 75, 90, 120 minutes post-administration.The results showed...
Milk produced by dairy cows is a complex combination of many components. However, at present, changes in only few milk components (e.g., fat, protein, and lactose) during the estrus cycle have been documented. Mid-infrared (MIR) spectroscopy worldwide method routinely used for analysis, as MIR spectra reflect global composition milk. Therefore, this study aimed to investigate production traits (fat, lactose, urea, total solids (TS), solid not fat (SnF)) due estrus. Cows that were...
Background: Avian species play a vital role in livelihood of human beings throughout the world, especially developing countries.Backyard poultry provides to large and small farmers, while industry has lead raising economic resources country, agricultural sector.This study was conducted evaluate effect housing system enrichment on performance, behavior meat quality Egyptian geese.Materials Methods: Sixty geese were divided into 2 groups, 30 birds per group according system, first reared pen...
Background: When turkeys’ legs come in contact with their dropping during the growing stage results footpad dermatitis condition which affects poult's welfare and productivity. Aim: Our experiment aimed to detect impact of different bedding materials on wellbeing, performance turkey under Egyptian conditions. Methods: 180-day-old poults were allocated into three treatments. In treatment I, (60 each replicates (n = 20 birds) kept wood shavings (WS); second treatment, housed chopped wheat...
The greatest challenges facing dairy farmers is heat stress. summer season in Egypt relatively long. This experiment aimed to study the effect of stress on some haemato-biochemical parameters and growth performance suckling Friesian calves. Eighteen calves with an average body weight 30±1.5 kg were used assigned into two groups (n= 9). first group reared inside open pen without fans or sprinkling water. While second a well-ventilated as well as, sprinkled water daily from 10 a.m. 2 p.m....
Studying the behavioural patterns of animals in their house may help to understand needs, but there has been a little investigation home-cage behaviours commonly used inbred strains mice such as C57BL/6 and DBA/2. Therefore, understanding these is important for neuroscience research. For first time, this experiment was carried out investigate long-term effects housing conditions (single vs. group) on home cage behaviour DBA/2 mice, order reveal differences between response single-housing....
A study was carried out to evaluate the effect of group size on some behavioral patterns, body weight, measurements and hematological parameters domestic goat. Adult female Shiba goats (Carpa hircus) (n=12) were divided randomly 2 groups according size. The first contains 4 animals (small group) while second one 8 (large group). Behavior recorded by using contentious focal sampling throughout period study, growth measured every two weeks along whole blood samples collected monthly estimate...
