The effect of low-energy and high-fiber diets on induced molting in laying hens was evaluated. Forty Rhode Island Red hens were divided into four feeding schemes (FS): I) alfalfa meal (AM), II) wheat bran (WB), III) AM/WB (1: 1); ad libitum and, IV) control diet (30 g·day-1). Feed intake (FI), laying cessation (LC), body weight loss (BWL), energy balance (EB), laying restart (LR), weight and egg production were evaluated. The information was analyzed using mixed models. FI·hen-1 was lower in FS I (P < 0.05). The LC was higher (P < 0.05) in FS II (7.3 days). The AM led to the ideal BWL (25-30%) faster (16.9 days) with respect to the other FS (P < 0.05): range between 22.9 to 32.4 days. The LR was faster in FS II (P < 0.05): 12.3 days. Egg weight and production were not affected by FS (P > 0.05). Inducing molt in laying hens using AMbased FS offers advantages over conventional methods, accelerates body weight loss, ovarian reactivation time is minimized, and productivity is not altered.

Estrus synchronization is a strategy to improve the reproductive efficiency of the herd. The objective was to compare different dwells times of an intravaginal progestogen (CIDR) with a dose of PGF2α in the synchronization to estrus of hair sheeps. Thirty female hair sheeps were used, randomly assigned to one of three treatments. T1: intravaginal progestogen (PI) for 5 days (PI5; n=10), T2: PI for 7 days (PI7; n=10) and T3: PI for 9 days (PI9; n=10). The incidence and onset of estrus, parturition and prolificacy were observed. Data analysis was performed using the life time method, logistic regression models and negative binomial models. The incidence at estrus was not different (p> 0.05) among treatments (T1: 80.0, T2: 100.0 and T3: 100.0%). Onset to estrus was lower (p ≤ 0.0) for T1 (29.8 ± 2.9 h) compared to the rest of the treatments. No differences (p> 0.05) were observed for parturition (T1: 70.0, T2: 90.0 and T3: 90.0%) and prolificacy (T1: 1.4 ± 0.3, T2: 1.4 ± 0.3 and T3: 1.5 ± 0.3). It is feasible to use short synchronization protocols based on intravaginal progestogens (CIDR) with a dose of PGF2α and maintain the reproductive efficiency of the herd.

Sheep are a species exploited in different areas of production. They are prone to different pathogens, highlighting parasites such as Haemonchus contortus . The prevailing climate and husbandry management practices are considered the main factors driving the spatial and temporal distribution of the nematode. Its distribution is worldwide, causing economic losses due to morbidity and mortality, and prevalence studies have been reported in different countries such as India, Spain, Nigeria, and Mexico; therefore, the objective of this study was to determine the edaphoclimatic factors of the different zones of the municipality of Culiacan and the production system that influence the prevalence of Haemonchus spp. in lambs. The research was carried out in the municipality of Culiacan, Sinaloa, Mexico, over a period of one year. It was an observational study, which included 23 sheep production units distributed in 10 districts of the municipality, with a total of 1520 samples of feces from animals under 3 months of age. The feces were processed individually by flotation technique. The overall prevalence was 13.42 %, and the autumn season (OR 2.38 (1.69-3.34) P<0.001), valley zone (OR 2.70 (1.21-6.02); P<0.016) and extensive system (OR 4.81 (3.38-6.85); P<0.0001) were risk factors associated with the presence of the nematode in lambs, so they should be considered for the establishment of preventive measures and control of parasitosis.
