The possible effect of heat stress (HS), measured with the temperature-humidity index (THI) across seasons year (SY) upon milk production (MP), feed-to-milk efficiency (FME), and cow comfort (CC) was assessed in Holstein-Friesian cows northern-arid Mexico. Data from 2467 (2146 milking 321 dry) were recorded SY [spring (SP), summer (SM), autumn (AT), winter (WN)] between 2016 2019 an intensive dairy farm located Comarca Lagunera (25° NL) large fluctuations regarding ambient temperature solar...
Water is a vital resource for sustaining life and numerous processes within the transformation industry. It finite resource, albeit one that can be renewed, thus sustainable management imperative. To achieve this objective, it necessary to have appropriate tools assist with planning policies its management. This paper presents time series analysis approach measure predict pattern of water consumption by humans throughout subsectors (domestic, commercial, public sector, education, industry,...
The aim of this study was to evaluate effects free ferulic acid (FA) supplementation on productive performance, some blood metabolite concentrations, and carcass characteristics ewe lambs finished in a feedlot. Dorper×Pelibuey (n=20; BW=28.5±0.5 kg; age=5 mo) were individually housed pens assigned under randomized complete block design the following dietary treatments (n=10): daily feeding without (control) or with 300 mg FA/animal. feedlot period lasted 34 d then all slaughtered. Free FA...
Contents In ruminants, nutrition is one of the exogenous inputs affecting reproductive function at different levels hypothalamic–hypophyseal–gonadal axis. However, exact mechanisms or even identification signalling metabolic compounds by which affects still need further clarification. The role static body condition (BC) and its interaction with a short‐term protein supplementation (PL), on secretion hormones [growth hormone (GH), insulin insulin‐like growth factor‐1 (IGF‐1)], as well LH...
Abstract Ten non‐lactating multiparous Pelibuey breed ewes were housed in a corral to evaluate the effects of summer thermal stress on physiologic variables, estrous behavior, ovulation and corpus luteum functionality under natural conditions an arid region. In autumn, daily detection with ram fitted apron blood sample collections performed during two cycles. An environment heat was detected thermoneutral autumn. Rectal temperature respiratory frequency greater ( P < 0.01) than autumn...
The objective of this study was to analyse the reproductive performance hybrid (Yorkshire x Landrace) gilts/ sows in relation temperature-humidity index (THI) at artificial insemination (AI), season AI, occurrence estrus >8 d post- weaning, repeated estrus, technique (cervical, CAI or post-cervical, PCAI) and parity. Data included 8851 records (1771 for gilts 7080 sows) from a pig farm sub-tropical zone (THI ranged 72.9 January 81.8 June). A decrease pregnancy rate (PR, 89.8 vs 93.0%;...
This study characterized the environmental–climatic trends occurring in largest dairy cattle intensive production cluster under arid land conditions northern Mexico. The was based on Temperature Humidity Index (THI); it aimed to identify number of days with THI values ≥68 as a bio-marker heat stress (HS) and evaluate possible HS effect upon milk cows. Climate data were obtained every 10 min five farms across years (i.e., 2015–2020). divided into four subclasses, 68–71, 72–76, 77–79, ≥80,...
The effect of beta-carotene supplementation upon luteal activity, measured as number (CLT) and volume (VLT) corpus luteum, P4 synthesis in goats, was evaluated. Goats (n = 22, 34 months) were randomly assigned to one two experimental groups: (i) [Beta, n 10; body weight (BW 44.8 +/- 1.45 kg), condition score (BCS 3.25 0.07)], (ii) Control (Control, 12; BW 45.30 1.32 kg, BCS 3.33 0.06). Upon oestrus synchronization, the Beta group received 50 mg per day during 35 days pre- 17 post-ovulation....
This study evaluated the effect of nutritional supplementation and socio-sexual cues upon reproductive efficiency goats exposed to male under rangeland grazing conditions (22°N). Criollo (n = 73) were distributed in four experimental groups: (1) continuous males (CM, n 19) which 2) remained together with females from 7 March 28 July; (2) supplemented (SM, 16) kept separately individually 18% crude protein 2.77 Mcal ME kg–1 DM, during a 30-day period; (3) female (SM + FE, 19), maintained...
The present study evaluated possible modulation of the buck effect by nutritional and metabolic cues during transition to breeding season in adult goats with divergent bodyweight (BW) body condition (BCS) at 27°N. In mid-February, (Boer × Spanish, n = 32) were assigned receive one following two experimental diets fulfill different allowances requirements: (1) 100% (n 16; BW 52.3 ± 1.5 kg, BCS 1.6 0.1 units; T-100) or (2) 150% 60.9 2.4 T-150) from February August. Blood samples collected...
The aim of the present study was to use a non-linear regression approach investigate relationship between litter birthweight and size five breeds goat under intensive conditions in hot arid environment. Litter-size litter-weight data on 20 117 kids from 13 685 litters representing breeds, namely Saanen, Toggenburg, French Alpine, Anglo-Nubian Granadina, were compared evaluate this relationship. Regardless breed, for born as twins, triplets quadruplets was, average, 92%, 87% 83%,...
