The efficiency of boric acid as an alternate to NaCl for the preservation of cattle hides
AbstractThe fresh buffalo hides (n = 6) were cut into two equal parts and categorized into three equal groups. The first group was treated with 50% NaCl; the second group hides were treated with 5% of boric acid (BA), and the third group hides were with NaCl + BA (10:1). Hair loss was seen at the sample margins of hides trea ted with 50% NaCl, with a slight odor. In the second group, there was neither hair loss nor a pungent smell was felt. The nitrogen content of the preserved hide was measured at different durations during the experimental period, i.e., 0 h, 24 h on day 7th, and day 14th. The nitrogen level red...

Substitution of soyabean meal by faba bean improves body weight, sperm production and testosterone concentration in mature Queue Fine de l ’Ouest rams
AbstractThe current study aimed at investigating the effects of partial or total substitution of soybean meal with faba bean on reproductive parameters of Queue Fine de l ’Ouest rams. Eighteen adult rams (49.8 ± 3.7 kg and 2.4 ± 1.5 years old) were divided into three homogenous groups. Rams received oat hay ad libitum and 3 types of concentrate (33 g/BW0.75) where soybean meal was the main protein source (SBM diet,n = 6), partially (50%, SBMFB diet,n = 6) or totally (100% FB diet,n = 6) substituted in nitrogen basis by local faba bean. The volume of ejaculate, sperm concentration and sperm mortality rate were measured ...

Economic analysis of bovine brucellosis control in the Rond ônia state, Brazil
AbstractBovine brucellosis, mainly caused byBrucella abortus, is a worldwide distribution anthropozoonosis that causes great economic losses. In 2001, Brazil launched the National Program for the Control and Eradication of Brucellosis and Tuberculosis (PNCEBT). Contemporaneously, a great effort to characterize the epidemiology of the disease in Brazilian states was started. In the state of Rond ônia, a first epidemiological study was carried out in 2004, revealing a prevalence of 35.2% of infected herds and 6.22% of seropositive females. In 2014, after a successful heifer vaccination program with strain 19 (S19), a second...

Effect of physically effective neutral detergent fiber on nutrient intake and digestibility, ruminal and blood parameters, and ingestive behavior of confined beef cattle
AbstractWe aimed to evaluate the effect of levels of physically effective neutral detergent fiber from forage (NDFfor) on confined cattle ’s metabolism and ingestive behavior. Four crossbred steers (514.0 ± 4.54 kg BW) rumen-cannulated were used. The animals were randomly distributed in a 4×4 Latin square design, and the treatments were diets with 9.5%, 5.5%, 2.5%, and 0.0% NDF from whole plant corn silage. The trial was divided i nto 4 periods of 21 days. The dry matter, organic matter (OM), crude protein, neutral detergent fiber (NDF), physically effective NDF 8mm (peNDF8mm) and NDF1.18mm intakes, and the digestibili...

Effect of increasing levels of Leucaena leucocephala seeds to grass pellets on performance of grower rabbits
AbstractThe study was carried out to determine the chemical composition of composite pellets ofMegathyrsus maximus containingLeucaena leucocephala seed meal at the varying level and growth responses, as well as haematological and serum biochemical of rabbits, fed the pellets for 60 days. The treatment consists ofM. maximus andL. leucocephala—100:0, 90:10, 80:20, 70:30 and 60:40, respectively. Results revealed an increase (P< 0.05) in the proximate composition of the grass pellets with an increase in seed inclusion while there was a reduction (P< 0.05) in the NDF contents of the pellets. An increase in the tannin co...

Use of thermography and physiological rate to assess heat tolerance in cattle breeds
Abstract Thermography has grown in use in recent years. It is a valuable tool for measuring animal heat tolerance under heat stress conditions since it is a non-invasive, safe and practical methodology. Physiological variables such as respiration rate and eye temperature, and environmental variables such as air temperature and wet bulb temperature were analysed in animals from nine cattle breeds (Angus, Braford, Brangus, Canchim, Charolais, Hereford, Nelore, Simmental and Santa Gertrudis) and one bubaline (Mediterranean) at Rio Grande do Sul, Brazil. Positive correlations were observed between air temperature and respir...

West African Dwarf goat populations of tropical rainforest zone: application of multivariate analysis tools on their characterization using morpho-biometric traits
AbstractThis research was carried out to characterize the West African Dwarf (WAD) goats using multivariate approach based on their morpho-biometric traits in the tropical rainforest zone of Nigeria. Data on four physical qualitative traits, six morphology indicators, and nine morphological characters were generated from 279 goats. Descriptive statistics, non-parametric analysis and one-way approach of ANOVA with post hoc tests, discriminant analysis (canonical), principal component analysis (categorical), and regression tree analysis were employed to discern the effects of location and sex on the parameters, as well as ch...

A farmer-friendly tool for estimation of weights of pigs kept by smallholder farmers in Uganda
AbstractPig keeping is important to the livelihoods of many rural Ugandans. Pigs are typically sold based on live weight or a carcass weight derived from this; however this weight is commonly estimated due to the lack of access to scales. Here, we explore the development of a weigh band for more accurate weight determination and potentially increased farmer bargaining power on sale price. Pig weights and varied body measurements (heart girth, height, and length) were collected on 764 pigs of different ages, sex, and breed types, from 157 smallholder pig keeping households in Central and Western Uganda. Mixed-effects linear...

The use of purple carrot powder in the diet of laying quails improved some egg quality characteristics, including antioxidant capacity
AbstractThe goal of the current experiment was to investigate the effect of dietary concentrations of purple carrot powder (PCP) on performance, egg production, egg quality, and the antioxidant capacity of the yolk in laying quails. A total of one hundred and fifty 22-week-old Japanese laying quails were allotted to 5 dietary treatments each with 6 replicates of 5 quails. Quails were allocated to five dietary treatments (0, 0.1, 0.2, 0.3, and 0.4%) with PCP addition at an increasing level from 0 to 4000  mg/kg diet respectively, which were fedad-libitum throughout the duration of the experiment. No differences were detect...

Methionine, cysteine, and butylated hydroxytoluene enhance cryosurvival of ram semen on post-thaw and post-incubation time points
This study was designed to investigate the different doses of methionine (2.5 and 5  mM), cysteine (1 and 2 mM), and butylated hydroxytoluene (BHT) (1 and 2 mM) for ram semen cryopreservation on post-thaw and post-incubation (6 h) time points over spermatological parameters. Semen samples were collected from Kivircik rams via electro-ejaculator in breeding season. After essenti al spermatological evaluations, appropriate samples were pooled then split into 7 equal aliquots to create study groups (antioxidant free control, 2.5 mM methionine, 5 mM methionine, 1 mM cysteine, 2 mM cysteine, 1 mM BHT, and 2 mM BHT). S...

Thermoregulatory capacity of goat kids from birth to weaning in a dry hot climate
This study aimed to evaluate the thermoregulatory capacity and performance of Saanen goat kids from birth to weaning in a hot climate. Twelve newborn males and female goat kids with an initial body weight of 4.17 ± 0.81 kg were used. Physiological responses, climatic variables, and biometric traits data were collected. Univariate and multivariate analysis techniques were used. Heart rate (HR) was high up to the 6th week of life, with a reduction from the 7th week on (P< 0.001). Rectal temperature (RT) was lower in the first 2 weeks (P< 0.001), with an increase and stabilization occurring in the 7th and 8th weeks. Co...

Water scarcity can be a critical limitation for the poultry industry
AbstractWater is essential for various physiological functions and the productive performance of animals. However, with climatic uncertainties exacerbated by climatic changes, water could become a scarce nutrient shortly. This is already the case in one-third of the world ’s countries, which are under medium to high levels of water stress. Accordingly, with the growth of poultry production, the availability of water at ad libitum level may not be guaranteed, and birds can be under water restriction for variable periods. Thus, this article aims at attracting the att ention of animal scientists to the freshwater shortage c...
