Effect of pomegranate ( Punica granatum) anthelmintic treatment on milk production in dairy sheep naturally infected with gastrointestinal nematodes. Front Vet Sci 2024; 11:1347151.

Abstract
Anthelmintic drug resistance has proliferated across Europe in sheep gastrointestinal nematodes (GINs). Sheep welfare and health are adversely impacted by these phenomena, which also have an impact on productivity. Finding alternatives for controlling GINs in sheep is thus of utmost importance. In this study, the anthelmintic effectiveness (AE) of a Calabrian ethnoveterinary aqueous macerate based on Punica granatum (whole fruits) was assessed in Comisana pregnant sheep. Furthermore, an examination, both qualitative and quantitative, was conducted on milk. Forty-five sheep were selected for the investigation. The sheep were divided by age, weight, physiological state (pluripara at 20 days before parturition), and eggs per gram of feces (EPG) into three homogeneous groups of 15 animals each: PG received a single oral dosage of P. granatum macerate at a rate of 50 mL per sheep; AG, treated with albendazole, was administered orally at 3.75 mg/kg/bw; and CG received no treatment. Timelines were as follows: D0, treatments, group assignment, fecal sampling, and AE assessment; D7, D14, D21, fecal sampling, and AE evaluation. The FLOTAC technique was used to evaluate the individual GIN fecal egg count (FEC) using a sodium chloride flotation solution (specific gravity = 1.20) and 100 × (1-[T2/C2]) as the formula for evaluating FEC reduction. Following the lambs' weaning, milk was collected on the following days (DL) in order to quantify production: DL35, DL42, DL49, DL56, DL63, DL70, DL77, and DL84. The amount of milk produced by every animal was measured and reported in milliliters (ml) for quantitative evaluations. Using MilkoScan TM fT + foss electric, Denmark, the quality of the milk (casein, lactose, protein concentration, and fat, expressed as a percentage) was assessed. The macerate demonstrated a considerable AE (51.8%). Moreover, its use has resulted in higher milk production rates quantitatively (15.5%) and qualitatively (5.12% protein, 4.12% casein, 4.21% lactose, and 8.18% fat). The study showed that green veterinary pharmacology could be the easiest future approach to counteracting anthelmintic resistance in sheep husbandry.

Abstract
Maternal behavior has been related to ewe's reactivity, as more reactive ewes might have greater risk of presenting worse maternal ability. This study aimed to determine the association between maternal behavior score (MBS) of Corriedale ewes with their physiological and behavioral variables measured at weaning of their offspring within two handling systems. Data from 335 ewes with average (± SE) age of 3.1 ± 1.8 years and 46.5 ± 6.1 kg of body weight were used. Experimental farms were classified into two handling systems: intensive (n = 3) and extensive (n = 2), based on stocking density and nature of human-animal relationships. Maternal behavior was evaluated in the field within 24 h after delivery, using a 6-rated scale (1 = poor to 6 = excellent). This scale takes into account the distance the ewe takes from the lamb when the lamb is restrained by an observer. The temperament of the ewes was evaluated during an arena test, at the weaning of the lambs, and was divided into two phases: social isolation and human presence. Data were subjected to principal component analysis and logistic regression. Logistic regression of principal factor (PF) scores in MBS showed that physical activity during the isolation phase increased in 1.57 (CI: 1.02 to 2.42; P < 0.05) the probability of extensively handling ewes showing high MBS (≥4), while in intensively handling ewes, logistic regression showed that the number of vocalizations in both phases of the arena test increased in 1.64 (CI: 1.12 to 2.4; P < 0.05) the probability of ewes having high MBS. Albeit the handling systems are not comparable, MBS was positively associated with some behavioral variables measured at the arena test.

J Anim Physiol Anim Nutr (Berl) 2021; 106:250-257. [PMID: 34291505 DOI: 10.1111/jpn.13609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Revised: 04/29/2021] [Accepted: 06/12/2021] [Indexed: 11/28/2022]
Abstract
Pre-weaning nutrition has significant influence on post-weaning performance of lambs. Strategic weaning management on milk replacer allowance at this phase can be a promising approach for harvesting desired carcass trait in finisher phase. Therefore, present experiment aimed economizing pre-weaning weight gain in lambs by feeding milk replacer and subsequently minimizing weaning age. A study of 90 days duration was conducted to determine the production performance, nutrient utilization and rumen fermentation of lambs on milk replacer allowance at different weaning age. Sixty-six Malpura lambs (10 days of age) were randomly divided into 3 equal groups. Lambs in control group were allowed conventional free suckling of dam up to 90 day of age, whereas lambs in the two treatment groups, that is W60 and W90 were offered milk replacer and weaned at 60 and 90 days, respectively. Lambs in all groups were offered ad-libitum creep mixture, Ziziphus nummularia leaves, Vigna unguiculata hay and fresh Ailanthus excelsa leaves. Overall weight gain was 12.7 per cent higher (p < 0.05) in W90 than control whereas in W60 group it was statistically comparable with both control and W90 groups. Overall average daily gain was 12.1 per cent higher (p < 0.05) in W90 group as compared to control. In case of nutrient digestibility, there was significant depression of dry matter (DM), organic matter (OM), crude protein (CP) and neutral detergent fibre (NDF) by 16.9, 17.2, 9.3 and 32.0 per cent in W60 than control; however, in W90, CP digestibility was higher (p < 0.05) than control and W60. Considering economic analysis, the net return obtained from W90 (90 days weaning plus milk replacer allowance) was more 20.0 per cent higher than control. Therefore, it can be concluded that lamb rearing on milk replacer and weaning at 90 days have a sustained positive effect on lambs' production performance and is more profitable than the practice of milk replacer allowance and early weaning in semiarid conditions.

Abstract
We investigated the impact of Norway's current zonal carnivore management system for four large carnivore species on sheep farming. Sheep losses increased when the large carnivores were reintroduced, but has declined again after the introduction of the zoning management system. The total number of sheep increased outside, but declined slightly inside the management zones. The total sheep production increased, but sheep farming was still lost as a source of income for many farmers. The use of the grazing resources became more extensive. Losses decreased because sheep were removed from the open outfield pastures and many farmers gave up sheep farming. While wolves expel sheep farming from the outfield grazing areas, small herds can still be kept in fenced enclosures. Bears are in every respect incompatible with sheep farming. Farmers adjust to the seasonal and more predictable behavior of lynx and wolverine, although these species also may cause serious losses when present. The mitigating efforts are costly and lead to reduced animal welfare and lower income for the farmers, although farmers in peri-urban areas increasingly are keeping sheep as an avocation. There is a spillover effect of the zoning strategy in the sense that there is substantial loss of livestock to carnivores outside, but geographically near the management zones. The carnivore management policy used in Norway is a reasonably successful management strategy when the goal is to separate livestock from carnivores and decrease the losses, but the burdens are unequally distributed and farmers inside the management zones are at an economic disadvantage.
